The daily temperatures for the winter months in Virginia are Normally distributed with a mean of 59°F and a
standard deviation of 10'F. The daily temperatures for the winter months in California are Normally distributed with
a mean of 64°F and a standard deviation of 12°F. Random samples of 10 temperatures are taken from the winter
months for both Virginia and California. The mean temperature is recorded for both samples. Let , -ă, represent
the difference in the mean temperatures for the winter months in Virginia and California. Which of the following
represents the standard deviation of the sampling distribution for 7, -7?
