elp 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. (a) Determine a point estimate for the population mean. A point estimate for the population mean is 5.04. (Round to two decimal places as needed.) (... OB. There is a 95% probability that the true mean pH of rain water is between OC. If repeated samples are taken, 95% of them will have a sample pH of rain water between 5.20 5.02 5.43 and (b) Construct and interpret a 95% confidence interval for the mean pH of rainwater. Select the correct choice below and fill in the answer boxes to complete your choice. (Use ascending order. Round to two decimal places as needed.). OA. There is 95% confidence that the population mean pH of rain water is between and 5.72 4.57 4.76 and 5.24 4.74 4.56 Clear all 4.80 5.19 5.30 Check answer
