The security department of a factory wants to know whether thetrue average time required by the night guard to walk his round is30 minutes. If, in a random sample of 45 rounds, the night guardaveraged 30.9 minutes with a standard deviation of 1.8 minutes,determine whether this is sufficient evidence to reject the nullhypothesis μ=30 minutes in favor of the alternative hypothesis μ≠30minutes. Use the 0.05 level of significance.
