We collect a random sample of 15 apartments, then measure the square footage of each one with the resulting summary statistics:

Sample mean: 1237

Sample standard deviation: 11.5

Sample size: 15

1. Determine whether to use a t-test or z-test.

2. Calculate the appropriate test statistic.

3. Identify the critical value for a .05 significance level.

4. Compute the p-value.

5. Make a conclusion. Do we reject or fail to reject the null hypothesis? Does our data support the claim?
