Assume that your uncle holds just one stock, East Coast Bank (ECB), which he thinks has very little risk. You obtain the following forecasted returns data for West Coast Bank (WCB) for next year. Assume the possibility of different states of the economy is the same for the next year.

Recession ECB 40% WCB 40% Below average ECB -10% WCB 15% Average ECB 35% WCB -5% Above average ECB -5% WCB -10% Booming ECB 15% WCB 35%

a) Calculated the expected return and stand-alone risk for ECB and WCB respectively

b) Based on your calculation in part a), would you recommend your uncle to do a portfolio of ECB and WCB? Explain.

c)Assume that for now, the market return is 7% and the risk-free return is 2%. What is the beta of stock ECB and stock WCB respectively? Assume the two stocks are in equilibrium.

d) Please comment on your uncle's opinion that ECB has very little risk. Briefly state your reasons.

A recent study of undergraduates looked at gender differences in dieting trends. There were 188 women and 103 men who participated in the survey. The table below summarizes whether a student tried a low-fat diet or not by gender:

(a) Fill in the missing cells of the table.

(b) Summarize the data numerically. What percent of each gender has tried low-fat diets? (Round your answers to two decimal places.)

(c) Test that there is no association between gender and the likelihood of trying a low-fat diet. (Round your χ² to three decimal places, and round your P-value to four decimal places.)

Problem: Your have been asked by a cell phone service provider to write a program that will calculate the amount of a customer’s monthly bill. Write a C++ program that will calculate the amount of the bill given the number of lines and the amount of minutes used during the month. Unlimited texting is also offered. '

The cellular service provider offers the following options and pricing: One line for $6/month base cost. Two lines for $12/month base cost.

The voice rates are as follows:

• No minutes: $0

• 1-400 minutes: $9 total

• 401-800 minutes: $16 total

• over 800 minutes: $16 + 1.9 cents/minute over 800 Unlimited texting is $5 extra.

Input: The program should ask the user if they have (A) one line or (B) two lines. Then the program should ask the user to input the number of minutes used in the month (no fractional amounts) Then the program should ask if the user has unlimited text messages (Y or N).

For the first two input values, use an if statement to perform input validation. The user should select only A, or B for the number of lines, and the minutes should be between 0 and 44640 (inclusive).

If either input is invalid, the program should ask the user to reenter the value (but only once, no looping).

Do not validate the response to the last question. 1 Processing: Compute the amount of the monthly bill according to the descriptions above.

If the user answered ‘y’ or ‘Y’ to the last question, your program should add $5 to the bill.

Output: Display the amount of the monthly bill with a dollar sign and formatted to 2 decimal places.

Here are 5 different sample executions of the program: How many lines: A. One line B. Two lines A Enter the total number of minutes used during the month: 100 Unlimited text messages? (Y/N): N The amount due for the month is $15.00

How many lines: A. One line B. Two lines B Enter the total number of minutes used during the month: 750 Unlimited text messages? (Y/N): Y The amount due for the month is $33.00

How many lines: A. One line B. Two lines A Enter the total number of minutes used during the month: 850 Unlimited text messages? (Y/N): Y The amount due for the month is $27.95

How many lines: A. One line B. Two lines A Enter the total number of minutes used during the month: 803 Unlimited text messages? (Y/N): y The amount due for the month is $27.06 2 How many lines: A. One line B. Two lines C Please enter A, or B: A Enter the total number of minutes used during the month: 1234567 Please enter a number between 0 and 44640 for the minutes: 500 Unlimited text messages? (Y/N): n The amount due for the month is $22.00

Moerdyk & Co. is considering Projects S and L, whose cash flows are shown below. These projects are mutually exclusive, equally risky, and not repeatable. If the decision is made by choosing the project with the higher IRR, how much value will be forgone? Note that under certain conditions choosing projects on the basis of the IRR will not cause any value to be lost because the one with the higher IRR will also have the higher NPV, i.e., no conflict will exist.

Noonan syndrome is a genetic condition that can affect the heart, growth, blood clotting, and mental and physical development. Noonan et al. examined the stature of men and women with Noonan syndrome. The study contained 29 male and 44 female adults. One of the cut-off values used to assess the stature was the third percentile of adult height. 24 of the females fell below the third percentile of female adult height and 11 of the males fell below the third percentile of adult male height.

a) Present the information and the data given in the problem in a 2 x 2 contingency table format.

b) What are the two categorical variables involved in this study?

c) Can the two categorical variables involved in this study be tested for independence (no association)? Why or why not?

d) Can the proportion of males who fall below their respective third percentile adult height and the proportion of females who fall below their respective third percentile adult height be tested for their homogeneity ? Why or why not?

The data below shows the titles of ten movies from 2018, the production budget and domestic box office receipts (in millions). For example, Black Panther's budget was $200 million and the box office revenues in the US totaled $700 million.

The mean production budget is 76.00 and its standard deviation is 55.68.

The mean Domestic Box office revenue is 190.94 and its standard deviation is 198.10.

The correlation coefficient between the two variables is 0.81

[Useful formulas: slope=rSy/Sx and intercept = mean of Y – (slope * mean of X)]

I believe that movies that spend more in production end up receiving more in box office revenues.

You run a regression of BUDGET on DOMESTIC BOX OFFICE.

According to the regression, for each additional million dollars spent on the budget, do box office receipts increase or decrease?  

by how much? (only use one decimal place in your answer)

6. There are two main ways to describe how loud a sound is. One is that you can describe its intensity, I, measured in W/m2, which is the amount of energy per unit time, per unit area, transported by the sound. However, this is not very close to the human experience of sound loudness. The human experience of loudness (actually like the way most of our senses work) is that each factor of 10 in intensity sounds like the same sized “step” in loudness. In other words, in our experience of sound, the difference between 0.01 W/m2 and 0.1 W/m2, seems the same as the difference between 0.1 W/m2 and 1 W/m2. For this reason, when talking about loudness we often use the “decibel scale”, defined by

   ?I? β = (10dB)log I0

   where I is the sound intensity, I0 is a reference intensity and β is the loudness in decibels. A common choice for I0 is the “threshold of hearing”, which for a typical person is I0 = 1 × 10−12 W/m2.

   1. (a) What intensity corresponds to β = 0 dB? Does 0 dB mean “no sound”?

   2. (b) The “threshold of pain” (hopefully the name makes it clear what this means...) is 130 dB. What sound intensity

      does this correspond to?

   3. (c) Some sound has a loudness of 50 dB. Another sound has 1200 times the intensity of the first sound. What is the loudness of the second sound?

1. A cognitive psychologist believes that memory for pictures is superior to memory for words. To test this hypothesis, the psychologist performs an experiment in which students from an introductory psychology class are used as participants. Ten randomly selected students view 30 slides with nouns printed on them, and another group of eight randomly selected students views slides with pictures of the same nouns. Each slide is presented for 4 seconds. After viewing the slides, participants are given a recall test, and the number of correctly remembered items is measured. The summary data follow:

Nouns     Pictures

n₁ = 10      n₂ = 8

M₁ = 20    M₂ = 22

SS₁ = 30   SS₂ = 40

Is there a difference between nouns and pictures in the number of words recalled? Use a two-tailed test with α = 0.05.

(1) What type of statistical test is appropriate for this research question?

(2) State the null and alternative hypotheses using statistical notation OR using plain English (a sentence for each).

(3) What are the degrees of freedom and critical t-values for this test?

(4) Calculate the pooled variance.

(5) Compute the test statistic

(6) What is your decision? And what does that decision mean, or how would you interpret/explain your decision?

(7) Construct the 95% confidence interval for the mean difference between the two conditions, µ₁-µ₂.

(8) Would you reject or fail to reject H₀ based on the 95% confidence interval? How do you know?
