The following data represent the pH of rain for a random sample of 12 rain dates in a particular region. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers. The sample standard deviation is a 0.331. Construct and interpret a 95% confidence interval for the standard deviation pH of rainwater in this region. 4.54 5.19 4.99 4.69 4.68 4.85 5.75 4.71 5.02 4.81 4.65 4.67 Click the icon to view the table of critical values of the chi-square distribution Select the correct choice below and fill in the answer boxes to complete your choice.
