Suppose 400 draws are taken at random from a box. The actual Ave is 58.8 with an SD of 27. The null Hypothesis says the Ave is 56 while the Alternative hypothesis says the Ave is more than 56. Compute the P-value and either reject of accept the null hypothesis. P-value is 2.05% and reject the null hypothesis P-value is 2.02% and reject the null hypothesis P-value is 2.02% and accept the null hypothesis P-value is 1.99% and reject the null hypothesis P-value is 1.99% and accept the null hypothesis
