If you were on the recruiting team to find a new
CEO for a company where the board mandate was to focus on embedding innovation into the DNA of the company, what attributes would you describe as being the "must-haves?"

Data on the fuel economy of several 2010 model vehicles are given in the accompanying table. Complete parts​ (a) and​ (b) below.

​a) Find and interpret a​ 95% confidence interval for the gas mileage of 2010 vehicles. Select the correct choice below and fill in the answer boxes within your choice.

​(Round to two decimal places as needed. Use ascending​ order.)

A.One is​ 95% confident that the true mean gas mileage for cars like the ones in the sample is between __ mpg and ___mpg.

B.The true mean gas mileage for cars like the ones in the sample is between ___mpg and ___mpg​ 95% of the time.

C.​95% of all cars like the ones in the sample have gas mileages between ___mpg and ___ mpg

D.One is​ 95% confident that the gas mileage of a randomly selected car like the ones in the sample is between ___ mpg and ___ mpg

​b) Does this confidence interval capture the mean gas mileage for all 2010​ vehicles? Choose the correct answer below.

A.There is a​ 95% chance that this interval contains the true mean gas mileage for all 2010 vehicles.

B.Because the sample size is more than​ 10% of the​ population, the inferences drawn from the confidence interval are not valid.

C.Without knowing how the data were​ selected, one must be cautious about generalizing to all 2010 cars.

D.Assuming the population of 2010 gas mileages follows a Normal​ model, this confidence interval definitely captures the true mean.

After a catastrophic failure of your injection mold die, the production team has rebuilt the equipment and production is running smoothly again. However, management wants to be sure the quality after the repairs is the same as before. Taking it on faith that σ = 0.030 grams before the failure, you conduct a quick experiment on a batch produced after the failure, and you measure s = 0.036 grams from a random sample of 25 O-rings.

a) Based on this experiment, can you conclude the injection mold process is exhibiting the same variance before and after the repair? Show all of your work  

b) The management brings in another production batch, produced before the failure, and wants you to compare the variances of this batch with the batch from part (a). You collect 30 random O-rings from this batch and measure the sample standard deviation, s. Assuming a 2-sided alternative, what is the lowest value of s you could measure and still be able to conclude the two batches have identical variances? Show all of your work.

Claim: “Golfers who had one lesson with this instructor had an average increase of more than 15 yards in the distance of their drives.”

A random sample of 5 golfers who had attended a free trial lesson with this golf instructor was selected. Before the lesson, each of these golfers hit several drives from a tee, and the average distance for each golfer was recorded (in yards). This process was repeated after the lesson. Assume that the differences between the “before” and “after” distances are approximately normally distributed. Test the claim at the 0.1 significance level.

A.) Identify the correct HYPOTHESES
B.) Identify the value of the TEST STATISTIC
C.) Identify the value of the CRITICAL VALUE(S)
D.) Identify the P-VALUE
E.) Identify the CONCLUSION

6. Paired annual rates of return data are collected from 8 randomly selected investment funds before and after The Federal Reserve cuts down interest rates. The dataset and relevant summery results are given in the table below. Suppose you are a financial analyst interested in finding out whether investment funds’ mean rate of return is significantly different before and after the interest rate adjustment.
