Ject Ho because P-value> a. 14. Basic Computation: Find the Test Statistic, Corresponding P-value, and Conclude Test A random sample of size 16 from a normal distribution with = 3 produced a sample mean of 4.5. (a) Check Requirements Is the distribution normal? Explain. (b) Compute the sample test statistic z under the null hypothesis Ho: = 6.3. 2 (c) For H: < 6.3, estimate the P-value of the test statistic. (d) For a level of significance of 0.01 and the hypotheses of parts (b) and (c), do you reject or fail to reject the null hypothesis? Explain.
