The following data represents 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. 5.05 5.72 4.89 4.80 5.02 5.03 4.74 5.19 5.43 4.76 4.56 4.68 A. Determine a point estimate for the population mean? B. Construct and interpret a 95% confidence interval for the mean pH of rain water? a. there is a 95% probability that the true pH of rain water is between___ and ___ b. there is 95% confidence that the population mean of pH of rain is between __and __ c. if repeated samples are taken 95% of them will have a sample pH of rain water between __ and __ C. Construct and interpret a 99% confidence interval for the mean pH of rain water? a. there is a 99% probability that the true pH of rain water is between___ and ___ b. there is 99% confidence that the population mean of pH of rain is between __and __ c. if repeated samples are taken 99% of them will have a sample pH of rain water between __ and __ D. what happens to the interval as the level of confidence is changed. As the level of confidence increases, the width of the interval. This makes sense since.
