The following data represent the pH of rain for a random sample of 12 rain dates. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers.  (5.58, 5.72, 4.99, 4.80, 5.02, 4.60, 4.74, 5.19, 4.61, 4.76, 4.56, 5.69)

Determine a point estimate for the population mean?
