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. 5.30 5.72 4.57 5.24 4.80 5.19 5.02 4.74 ts 4.61 4.76 4.56 4.68 ts choice. nts (Use ascending order. Round to two decimal places as needed.) O A. If repeated samples are taken, 99% of them will have a sample pH of rain water between and me O B. There is a 99% probability that the true mean pH of rain water is between and nts There is 99% confidence that the population mean pH of rain water is between 4.61 and 5.26. ents (d) What happens to the interval as the level of confidence is changed? Explain why this is a logical result. nts As the level of confidence increases, the width of the interval increases. This makes sense since all confidence intervals of a given level of confidence have the same width. book
