Annual per capita consumption of milk is 21.6 gallons (Statistical Abstract of the United States: 2006). Being from the Midwest, you believe milk consumption is higher there and wish to support your opinion. A sample of 16 individuals from the midwestern town of Webster City showed a sample mean annual consumption of 24.1 gallons with a standard deviation of 4.8.
Compute the value of the test statistic. (Round to two decimal places)
What is the p-value? (Round to three decimal places).
At α=0.05, what is your conclusion?
Solution-
Test Statistic = 2.08
P-value = 0.027
by the test results
null hypothesis is rejected.
So, there is enough evidence to claim that milk consumption is higher in the Midwest.
