a Round of Golf on Your Typical Course Requires $\alpha$

Golf
A round of golf on your typical course requires at least 4.5 hours.A particular golf club claims that the average length of time to complete a round of golf on their course is less than 4.5 hours.To test this claim,the club sampled 15 golfers and recorded their time to finish their round.The sample average was 4.4 hours with a standard deviation of 0.8 hours.Assume the time to complete a round of golf is normally distributed and use $\alpha$ = 0.01.
-A random sample of 7 observations was drawn from a normal population.The following summations were computed: $\Sigma$ x_i = 63.5 and $\Sigma$ x_i ² = 580.2.
Test the following hypotheses: H₀: $\mu$ = 8,H₁: $\mu$ > 8,at the 1% significance level.
