Question
In this scenario, what is the test statistic?
• A budget controller would like to test the claim that the average monthly amount spent on travel expenses at a small
company is different than 65 hundred dollars.
• Sample size = 18 months
• Sample mean = 61.5 hundred dollars
• Sample standard deviation = 6.5 hundred dollars
Calculate the test statistic using the formula:
to =
Ort – x
where:
ī = sample mean
S = sample standard deviation,
• n = sample size, and
• Ho = population mean under the null hypothesis.
Round your answer to 2 decimal places.
