A safety group claims that the mean speed of drivers on a highway exceeds the posted speed limit of 65 miles per hour (mph). To investigate the safety group's claim, a random sample of 25 drivers is taken and the sample mean and sample standard deviation are 69 and 8 respectively. Does this give us evidence that the safety group's claim is correct? Give the null and alternative hypotheses for this test. OA. HON 569, H > 69 O B....

Floretta, a pitcher, claims that her pitch speed is less than 46 miles per hour, on average. Several of her teammates do not believe her, so she decides to do a hypothesis test, at a 5% significance level, to persuade them. She throws 24 pitches. The mean speed of the sample pitches is 37 miles per hour. Floretta knows from experience that the standard deviation for her pitch speed is 5 miles per hour. H0: μ=46; Ha: μ<46 α=0.05 (significance...
