The following data represent the pH of rain for a random sample of 12 rain dates in a particular region. A normal probability plot suggests the data could come from apopulation that is normally distributed. A boxplot indicates there are no outliers. The sample standard deviation is s = 0.335. Construct and interpret a 95% confidenceinterval for the standard deviation pH of rainwater in this region.4.505.245.064.774.664.675.654.675.094.834.724.54Click the icon to view the table of critical values of the chi-square distribution.Select the correct choice below and fill in the answer boxes to complete your choice.(Use ascending order.

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability.
