A national newspaper reported that the state with the longest mean life span is Hawaii, where the population mean life span is 81 years. A random sample of 20 obituary notices in the Honolulu Advertizer gave the following information about life span (in years) of Honolulu residents. 72 68 81 93 56 19 78 94 83 84 77 69 85 97 75 71 86 47 66 27 (i) Use a calculator with sample mean and standard deviation keys to find x and s.

USA Today reported that the population mean life span of people
who live in Hawaii is 77 years. A random sample of 20 obituary
notices gave a sample mean life span of ?̅= 71.4 years and a sample
standard deviation s = 20.65 years. Assuming that the life span of
people in Hawaii is normally distributed, does this indicate that
the population mean life span is less than 77 years? Use a 5% level
of significance.

#10. You are to determine if a new
online teaching model is better than the existing model, labelled
old. You administer random tests to a pre-selected group of
students first for material taught the old model and then under the
new model. The data is given in the Excel file and is labelled
problem # 10. Carry out an appropriate procedure in hypothesis
testing to determine if the new model is more effective for
learning.

Since we are attempting to examine the behavior of a class of
students, the behavior of an individual (as we calculated in
objective 1) is really of little concern to us. Assuming that there
are 30 students enrolled for a typical class, use the central limit
theorem to calculate the following:
• What would be the shape of the
distribution of the average class grade of these 30 students?
• What would be the average class
average of...
