We are not provided with the full details of the hypothesis test or the significance level, but from the table, we can see that the sample size is 30, the sample mean is 26.20, and the sample standard deviation is 6.11. To test the hypothesis that the population mean profit per customer is greater than $25, we can use a one-sample t-test with the formula t = (x̄ - μ) / (s / sqrt(n)), where x̄ is the sample mean, μ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size. Plugging in the values, we get t = (26.20 - 25) / (6.11 / sqrt(30)) = 1.867. This corresponds to choice C.
