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. Complete parts a) through d) below. 5.05 5.72 5.24 4.80 5.02 4.60 4.74 5.19 5.29 4.76 4.56 5.71 a Click the icon to view the table of critical tvalues. (a) Determine a point estimate for the population mean. A point estimate for the population mean is 5.06 . (Round to two decimal places as needed.) (h) Construct and interpret a 95% condence interval for the mean pH of rainwater. Select the correct choice below and ll in the answer boxes to complete your choice. (Use ascending order, Round to two decimal places as needed.) O A- There is a 95% probability that the true mean pH of rain water is between and O 5- There is 95% condence that the population mean pH of rain water is between and O C- If repeated samples are taken, 95% at them will have a sample pH of rain water between and
