I’m working on a mathematics question and need support to help me understand better.

Instructions
A night club owner has just changed ownership and the new owner has contracted G&B consulting to help decide the direction the club will take. Based on the local music scene, it would make the most sense to book either rock bands or country bands. The new owner is aware that a competing night club is hoping to attract new customers while the new club is getting itself established. Since these are the only two night clubs in town competing to book the same bands, whatever market share is gained by one is lost by the other making this a zero-sum game. The new club owner has hired you to find the optimum strategy for this situation.

1. Instructions
During the city’s mayoral race one of the candidates hires G&B Consulting. This candidate is a challenger from the same party as the incumbent mayor and is vying to be put on the ticket in the general election. She believes that the nomination will likely come down to what stance she takes on a proposed tax bill. The bill is for a tax increase that would subsidize education grants. Staying within traditional party lines would be advantageous to gaining support from the core constituency, but going against party lines on the issue would help sway swing voters and independents. The issue is bound to come up at an upcoming debate and she wants the help of G&B Consulting to determine an optimum strategy.

I’m working on a algebra discussion question and need an explanation to help me study.

Please see below a good solved example for 2019 for the population growth rate analysis. Please use the current year for your posts.
===========================================================

Let’s consider the state of Wisconsin in regard to population growth. As of 2019, the current population is 5,832,661. Wisconsin is the 23rd largest state in the country.

1. The population growth equation is:

P(t)=Poekt$P\left(t\right)=P_o{e}^{kt}$P$P$ ( t ) = P o e k t

Growth Rate = 0.35%

e = Euler’s number (constant) = 2.7183

Population in 2050:

t = 2050 – 2019 = 31 years

P(31) = 5,832,661*e0.0035(31) = 5,832,661*2.71830.1085 = 6501112.58044

The formula and calculations indicate that in 2050 the population of Wisconsin will be approx. 6,501,113.

2. To determine when the population will be doubled:

T=ln2/k

T=ln2/(0.0035) = 0.69/0.0035 =198.042051589

T=198

The population in Wisconsin will double in 198 years.

3. An additional real-world example that can be used for exponential or logarithmic equations is a working budget. If we want to find what our budget would be in 10 years (2029) or 20 years (2039) we can use the logarithmic equation to determine that.

Your task for this discussion is as follows:

1. Use the population growth equation to determine the expected population for a state (not already chosen by another student) in the year 2050. Make sure to cite any outside sources used to determine the current growth rate.
2. Determine when the population will double. (i.e. Doubling Time, T)
3. Discuss additional examples of real-world contexts that can be modeled using exponential or logarithmic equations.
4. In your responses to peers, compare your results and comment on their additional examples.

Exercises 8.1-7, 8.1-10, 8.4-1, 8.4-3, 8.4-6 .

8.1-7. Vitamin B6 is one of the vitamins in a multiple vita-min pill manufactured by a pharmaceutical company. The pills are produced with a mean of 50 mg of vitamin B6 per pill. The company believes that there is a deteriora-tion of 1 mg/month, so that after three months it expects that ? = 47. A consumer group suspects that ?< 47 after three months.

(a) Define a critical region to test H0: ? = 47 against H1: ?< 47 at an ? = 0.05 significance level based on a random sample of size n = 20.

(b) If the 20 pills yielded a mean of x = 46.94 with a stan-dard deviation of s = 0.15, what is your conclusion?

(c) What is the approximate p value of this test?

8.1-10. In a mechanical testing lab, acrylic glass strips are stretchedtofailure.Let X equal the change in length in mm before breaking. Assume that the distribution of X is N(?, ?2). We shall test the null hypothesis H0: ? = 5.70 against the alternative hypothesis H1: ?> 5.70, using n = 8 observations of X.

(a) Define the test statistic and a critical region that has a significance level of ? = 0.05. Sketch a figure showing this critical region.

(b) A random sample of eight observations of X yielded the following data: 5.71 5.80 6.03 5.87 6.22 5.92 5.57 5.83

Calculate the value of the test statistic and state your conclusion clearly.

(c) Give the approximate value of or bounds for the p-value of this test.

8.4-1. Let Y be b(100, p). To test H0: p = 0.08 against H1: p < 0.08, we reject H0 and accept H1 if and only if Y ? 6. (a) Determine the significance level ? of the test. (b) Find the probability of the Type II error if, in fact, p = 0.04.

8.4-3. Let Y be b(192, p). We reject H0: p = 0.75 and accept H1: p > 0.75 if and only if Y ? 152. Use the normal approximation to determine (a) ? = P(Y ? 152; p = 0.75). (b) ? = P(Y < 152) when p = 0.80.

8.4-6. It was claimed that 75% of all dentists recommend a certain brand of gum for their gum-chewing patients. A consumer group doubted this claim and decided to testH0: p = 0.75 against the alternative hypothesis H1: p < 0.75, where p is the proportion of dentists who recommend that brand of gum. A survey of 390 dentists found that 273 recommended the given brand of gum.

(a) Which hypothesis would you accept if the significance level is ? = 0.05?

(b) Which hypothesis would you accept if the significance level is ? = 0.01?

(c) Find the p-value for this test.

Hello. I was hoping that you would be able to assist me with this weeks discussion question. It only needs to be 175 words. I have attached the question as well as the chapter. Thank you

Question are attached in the document. all questions must be answered, it is said that should not take more than 4 hour max but you may use more time if it helps. Question 1-8 must be answered, here is a sample of one of the questions. PLease read the questions before you bid, I you cannot answer them pleased do not bid.

4. Many school districts pay for new school buildings with bond issues that must be approved by majority
vote in an election. Supporters of these bond issues typically argue that new buildings improve schools
and thereby boost housing values. A recent economics paper used RD to test whether passage of school
bonds caused housing values to rise.

(a) (5 pts) What is the assignment variable (a.k.a. the running variable)? Hint: time is not the
assignment variable.

(b) (10 pts) Explain how to use a basic sharp RD approach to estimate the eect of school bond
passage on housing values.

(c) (5 pts) Provide an equation that implements the approach you described in (b). Assume you
observe sale prices of individual homes. Be sure you properly subscript your variables.

I am prepping for my final and out of the 100 question study guide these are the questions I could not seem to work out or recall. I am wanting each question worked out with answer and step by step instructions and final answer including if it in some cases may be rounded to the nearest tenth or hundreth

I have the two questions that I need solved and an adequate explanation. You do not need to type, you can write if your handwriting is legible. Please bid only if you understand, can solve and explain adequately.
