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 or basic or alkaline. A random sample of lakes in Florida was taken and the pH was recorded for each lake. Summary statistics are given below. The primary question to answer is: "Is there evidence to indicate the mean pH of lakes in Florida is different than the neutral value of 7?" min 01 median Q3 max mean sd missing n 3.6 5.8 6.8 7.4 9.1 6.5906 1.2884 53 A 95% confidence interval for the mean pH level of all lakes in Florida is to be constructed. Fill in the blanks below with the correct values in the formula for this problem. Report all values to three decimal places. Use R Studio or a calculator to obtain the critical value.
