Answer:
A manager of a grocery store wants to determine if consumers are spending more than the national average.
Yes is the answer
Step-by-step explanation:
Given that the national average is $150.00 with a standard deviation of $30.20.
Sample size n =40
H0: x bar = mu
Ha: x bar >mu
(one tailed test for a single mean)
Sample average x bar = 160
Mean difference = 160-150 =10
std error = 30.20/sqrt 40
=4.775
Test statistic = 2.094
Z critical for 2.5% = 1.96 (one tailed)
Since test statistic > z critical we reject null hypothesis.
Hence Manager's contention is right.
