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 s = 0.287. Construct and interpret a 90% confidence interval for the standard deviation pH of rainwater in this region. Select the correct choice below and fill in the answer boxes to complete your choice. (Use ascending order. Round to three decimal places as needed.)
A. If repeated samples are taken, 90% of them will have the sample standard deviation between and
B. There is a 90% chance that the true population standard deviation is between and
C. There is 90% confidence that the population standard deviation is between and
