3. We found the mean number of years of education is 13.05 with a standard deviation of 3.02 among a total of 2,500 GSS respondents. Assuming that years of education is normally distributed, answer the following questions. a) If you have 13.-77 years of education, 1) what is your z score? 2) what is your percentile value? b) If your friend is in the 70th percentile, how many years of education does she have? c) How many people have between your years of education (i.e., 13.77) and your friend's years of education (i.e., 80th percentile)? d) Construct and interpret an estimate of the population mean number of years of edu- cation at the 95% level.

Question

3. We found the mean number of years of education is 13.05 with a standard deviation of
3.02 among a total of 2,500 GSS respondents. Assuming that years of education is normally
distributed, answer the following questions.
a) If you have 13.77 years of education, 1) what is your z score? 2) what is your percentile
value?
b) If your friend is in the 70h percentile, how many years of education does she have?
c) How many people have between your years of education (i.e., 13.77) and your friend's
years of education (i.e., 80th percentile)?
d) Construct and interpret an estimate of the population mean number of years of edu-
cation at the 95% level.

Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is ? = 19 inches. However, a survey reported that of a random sample of 51 fish caught, the mean length was x = 18.6 inches, with estimated standard deviation s = 2.9 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than ? = 19 inches? Use ? = 0.05. i-What is the value of the sample test statistic?
