Question 16 (2.5 points) We investigate the first serve success probability of Leylah Fernandez. In a data set, she tried 143 first serves and succeeded 94 times. We used the central limit theorem to estimate the 95% confidence interval of Leylah's first serve success probability. What is the length of the 95% confidence interval? (Compute your answer to the nearest 100th, e.g. 5.216 should be written as 5.22) Your Answer: Answer Question 17 (1.5 points) Suppose that you have the following regression results with a sample size of 100: Y =43.2 + 61.5X, R' = 0.54, SER = 1.52 (10.2) (7.4) We want test whether the slope coefficient is 45 or not. Construct a t-statistic to the nearest 100th digit. Your
