Do it step by step using Minitab WITH DETAILS

To study the relationship between number of study hours and passing rate of a stat course, a sample of 10 individuals is collected and the data is

Study Hours x 0 1 2 3 4 5 6 7 8   9

Passing Rate y 0.012385 0.038572 0.110161 0.214305 0.379475 0.577586 0.513681 0.593416 0.863329 0.888012

a, Find the 95% CI for β1.

b. Compute r and r 2 and interpret their meaning?

c. Let x = 1.25. Find the estimate mean value of passing rate, then find the 94% CI for the estimation of mean and the 94% PI for the prediction of an individual y

Please put step by step in Minitab For the 15-year period between 1995 and 2010, ABC’s monthly return had a standard deviation of 5%. Matthew, a certified financial analyst, wishes to establish whether the standard deviation witnessed during that period still adequately describes the long-term standard deviation of the company’s return. He collects data on the monthly returns recorded between 1st Jan. 2015 and 31st Dec. 2016 and computes a monthly standard deviation of 4%. Carry out a 5% test...
