A boxplot indicates there are no outliers. Complete parts a) through d) below. 5.05 5.72 5.24 4.80 5.02 4.59 4.74 5.19 5.29 4.76 4.56 5.70 LOADING... Click the icon to view the table of critical t-values. (a) Determine the population mean?

**(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.)

Lower Limit = 4.8068

Upper Limit =

Upper Limit = 5.3032

95% Confidence interval is ( 4.81 , 5.30 )

C. There is a 95 confidence that the population mean pH of rain water is between 4.81 and 5.30.
