A nursing professor was curious as to whether the students in a very large class

she was teaching who turned in their tests first scored differently from the overall

mean on the test. The overall mean score on the test was 75 with a standard

deviation of 10; the scores were approximately normally distributed. The mean

score for the first 20 tests was 78. Did the students turning in their tests first score

significantly

different from the mean?

A professor was curious as to whether the students in a very large class she was teaching, who turned in their tests first, scored differently from the class mean on the test. The μ on the test was 75 with σ = 10; the scores were approximately normally distributed. The mean score for the first 20 tests was 78. Did the students turning in their tests first score significantly different from the larger mean at the .05 level? a) Use...

COIN TOSSES In a large class of introductory Statistics students, the professor has each student toss a coin 16 times and calculate the proportion of his or her tosses that were heads. The students then report their results, and the professor plots a histogram of these several proportions. What shape would you expect this histogram to be? Why? Where do you expect the histogram to be centred? How much variability would you expect among these proportions? Explain why a Normal...

A researcher is curious if age makes a difference in whether or not students make use of the gym at a university. He takes a random sample of 30 days and counts the number of upperclassmen (Group 1) and underclassmen (Group 2) that use the gym each day. The data are below. The population standard deviation for underclassmen is known to be 22.57 and the population standard deviation for upperclassmen is known to be 13.57. Upper Classmen average = 202.4,...
