Compute the coefficient of correlation between the return on Target and the return on BMW. Is the relationship between the return on Target and the return on BMW weak? Why or why not? QUESTION 2 Construct and interpret the confidence interval for the population mean . The mean and the standard deviation of a random sample of 49 measurements are: X=60 S=3 Assume that the error level is 5%; that is, a=5%. QUESTION 3 Construct and interpret the confidence interval for gas price in Missouri. A random sample of 16 gas stations throughout Missouri was surveyed. The following is the summary statistics of the sample: X=1.8 S=1.2 Assume that the error level is 1%; that is, a=1%. QUESTION 4 Conduct the following test of hypothesis about the population mean : Ho100 : > 100 The mean and the standard deviation of a random sample of 16 measurements are: X=102 S =4 Assume that the error level is 10 % (a=10%)
