Question
ot
Nancy, an economist, would like to make the claim that the average weekly grocery budget for households in a small U.S.
city is less than $253. Nancy samples 18 households in the same city and obtains a sample mean of $229.60 spent on
18 PM
groceries per week.
At the 2.5% significance level, should Nancy reject or fail to reject the null hypothesis given the sample data below?
9 PM
Ho : u = $253 per week; Ha :u < $253 per week
0.025 (significance level)
a
ot
4 PM
test statistic = -0.75
Use the graph below to select the type of test (left-, right-, or two-tailed)
O PM
Then set the a and the test statistic to find the p-value. Use the results to determine whether to reject or fail to reject the
null hypothesis.
