# Question: With reference to Exercise 13 30 use suitable statistical software to

With reference to Exercise 13.30, use suitable statistical software to find the P-value that corresponds to the observed value of the test statistic. Use this P-value to rework the exercise.

In exercise

Five measurements of the tar content of a certain kind of cigarette yielded 14.5, 14.2, 14.4, 14.3, and 14.6 mg/cigarette. Assuming that the data are a random sample from a normal population, use the four steps on page 354 to show that at the 0.05 level of significance the null hypothesis µ = 14.0 must be rejected in favor of the alternative µ ≠ 14.0.
