The US vehicle sticker information states that you can expect 19 miles per gallon. It is desired to check the consistency of this information. Sixteen vehicles of the same model were tested. Assuming the miles per gallon X-N (μ, o²) and we take a random sample of n=16, we wish to test Ho : μ = 19 H : μ # 19 at the 5% significance level. We observe x = 18.16and s=1.48 where s is the sample standard deviation. The absolute value of the test statistic and the decision are

Assuming the miles per gallon X-N (μ, o²) and we take a random sample of n=16, we wish to test Ho : μ = 19 H : μ # 19 at the 5% significance level. We observe x = 18. 16and s=1.48 where s is the sample standard deviation. The absolute value of the test statistic and the decision are 2.12; reject the null hypothesis 2.27; reject the null hypothesis 1.96; do not reject the null hypothesis 1.60; do not reject the null hypothesis
