A reseаrcher is interested in the heights оf аll students аt a lоcal cоllege. The researcher randomly selects 45 students and finds a mean height of 68.52 inches with a standard deviation of 2.71 inches. (Round to 3 decimal places as needed) a. Construct a 90% confidence interval for the mean height of all students at this college: Point estimate = [a] Confidence interval (make sure you put the smaller value first): --> ([b], [c]) b. Is it plausible that the mean height of all students at this college is 67.5 inches? [d] (yes/no), because 67.5 [e] (is/is not) within the confidence interval. c. If the researcher wants to be within 0.30 inches of the true mean height with 90% confidence, how many students should they sample? (Use the standard deviation above as an estimated population standard deviation) [f]
