Use the p-value approach to conduct a hypothesis test for the following problem. provide detailed solutions in the four steps to hypothesis testing. the security department of a factory wants to know whether the true average time required by the night guard to walk his round is 30 minutes. if, in a random sample of 25 rounds, the night guard averaged 30.9 minutes with a standard deviation of 1.8 minutes, determine whether this is sufficient evidence to reject the null hypothesis μ=30 minutes in favor of the alternative hypothesis μ≠30 minutes. use the 0.05 level of significance. (assume that the population is normally distributed.)
