The t-test formula is (x̄ - μ) / (s/√n), where x̄ is the sample mean, μ is the hypothesized population mean, s is the standard deviation of the sample, and n is the sample size. Plugging in the values, we get (16.8 - 15) / (2.7/√25) = 2.81. This test statistic corresponds to a two-tailed test with a significance level of 0.05 and 23 degrees of freedom.
