a. variable Statistics, find the sample standard deviation for the data set. b. At a = 0.05, is there enough evidence to reject the claim that the community pool chlorine levels have a standard deviation of 0.46 ppm? c. The director of the community health department (a graduate of Mr. Sedgwick's Probability and Statistics class) realizes that the argument would be more convincing if the claim were moved to H, Rewrite the hypothesis statements so that it becomes a right-tailed test, and change the a to a = 0.02. Is there enough evidence to support this new claim?

Swimming Pool Chlorine Level A community center claims that the chlorine level in its swimming pool has a standard deviation of 0.46 parts per million (ppm). The community health department decides to test this claim and takes samples of the pool's chlorine level at 25 random times during a certain month. Here are those results: Chlorine Levels at the Community Pool (in ppm) 1.0 1.6 2.0 2.4 2.8 1.2 1.8 2.2 2.4 2.8 1.4 1.8 2.2 2.4 3.0 1.4 1.8 2.2 2.4 3.2 1.6 2.0 2.2 2.8 3.2 a.
