An orange grower is introducing a new variety of orange. The grower claims that the new oranges have a mean pH of 5. To test the claim, an independent researcher chose a random sample of 29 of the new oranges, finding they had a sample mean pH of 5.2 with a sample standard deviation of 0.5. Assume that the population of pH values of the new oranges is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject that ?, the mean pH of the new oranges, is 5. (a) State the null hypothesis Ho and the alternative hypothesis H? that you would use for the test. Ho: O H?: 0
