Lucy is using a one-sample t‑test based on a simple random sample of size n=31 to test the null hypothesis H0:μ=15.000 cm against the alternative H1:μ=/15.000 cm. The sample has mean x⎯⎯=15.106 cm and standard deviation is s=1.053 cm. Determine the value of the t‑statistic for this test. Give your answer to three decimal places.
