(c) Show all details of the test described in part (b) and use a 5 % significance level. Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistic = 1 p-value = i What is the conclusion? V Ho- If there is evidence that it is not neutral, does the mean appear to be more acidic or more alkaline?

Are Florida Lakes Acidic or Alkaline? The pH of a liquid is a measure of its acidity or alkalinity. Pure water has a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are basic, or alkaline. The dataset Florida Lakes gives information luding pH values, for a sample of lakes in Florida. Computer output of descriptive statistics for the pH ble is shown: Descriptive Statistics: pH Variable PH N* N 53 0 Mean 6.591 SE Mean 0.177 StDev 1.288 Minimum QI 3.600 5.800 Median 6.800 Q3 7.450 Maximum 9.100
