1. The advertised mean temperature of coffee from a national coffee shop chain is 162°F and with a standard
deviation is 9°F, with a left skewed distribution. If you repeatedly collected 36 samples of coffee across the
country, what will be the mean, standard deviation, and distribution of the sample means.
a) Mean
b) Standard deviation
c) Distribution
7. The scores of students on the ACT college entrance examination in 2001 had mean u =21.0 and standard
deviation o = 4.7. The distribution of scores is only roughly normal.
Now take an SRS of 50 students who took the ACT test.
a) What is the mean µg and standard deviation og of the sample mean score of these 50 students? (Round
answer to the nearest ten-thousandth, the fourth decimal place.)
