A sample of 40 sales receipts from a grocery store has x̄ = $137 and σ = $30.2. Use these values to test whether or not the mean sales at the grocery store are different from $150. Set α = 0.01.
Added by Jack P.
Step 1
- Null Hypothesis (H0): The mean sales at the grocery store are equal to $150. - Alternative Hypothesis (H1): The mean sales at the grocery store are not equal to $150. Show more…

Use the z -score formula, z=(x−μ/σ) , and the information below to find the mean, μ . Round your answer to one decimal place, if necessary. z=0.25, x=14.5, and σ=4.4

Conduct the appropriate test. A simple random sample of size $n=40$ is drawn from a population. The sample mean is found to be $108.5,$ and the sample standard deviation is found to be $17.9 .$ Test the claim that the population mean is greater than 100 at the $\alpha=0.05$ level of significance.

Putting It All Together: Which Method Do I Use?
Test the claim about the population mean $\mu$ at the level of significance $\alpha .$ Assume the population is normally distributed. If convenient, use technology. Claim: $\mu \leq 22,500 ; \alpha=0.01 ; \sigma=1200$ Sample statistics: $\bar{x}=23,500, n=45$
