Height data, collected from a statistics class, has a mean, X = 68.21 inches, and a standard deviation of s=4.01 inches. The sample size of the data was n = 36. Suppose the data collected could be considered a random sample of WCU students. Calculate the lower boundary of a 99% confidence z-interval. Give your answer as a decimal number rounded to 2 decimal places. INinto nu can use the calculator to find this solution or do this by hand)...

An instructor believes that students do not retain as much information from a lecture on a Friday compared to a Monday. To test this belief, the instructor teaches a small sample of college students some preselected material from a single topic on statistics on a Friday and on a Monday. All students received a test on the material. The differences in exam scores for material taught on Friday minus Monday are listed in the following table. Difference Scores (Friday −...

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 3737 beats per minute, the mean of the listed pulse rates is x=74.0 beats per minute, and their standard deviation is s=12.7 beats per minute. a. What is the difference between the pulse rate of 37 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c....
