The data in the accompanying table represent the rate of return of a certain company stock for 11 months, compared with the rate of retum of a certain index of 500 stocks. Both are in percent. Complete parts (a) through (d) b H₁ P₁0 D. HP-D H₁ B₁ D Determine the P-value for this hypothesis test value= (Round to three decimal places as needed) State the appropriate conclusion at the a-0.10 level of significance. Choose the correct answer below A. Do not reject Ho. There is sufficient evidence to conclude that a linear relation exists between the rate of return of the index and the rate of return of the company stock B. Reject Ho There is sufficient evidence to conclude that a linear relation exists between the rate of return of the index and the rate of return of the company stock c. Do not reject H, There is not sufficient evidence to conclude that a Inear relation exists between the rate of totam of the index and the rule of return of the company stock D. Reject H, There is not sufficient evidence to conclude that a linear relation exists between the rate of return of the index and the rate of return of the company stock c) Assuming the residuals are normally distributed, construct a 90% confidence interval for the slope of the true least squares regression line Lower bound (Round to four decimal places as needed) Upper bound. (Round to four decimal places as needed) d) What is the mean rate of return for the company stock if the rate of return of the index is 3 15%9
