c. Enter the data in R using arsenic = c(9.2, ..., 8.3), make graphs and compute numerical values necessary to describe the distribution, and record your work below. Use your work to describe the data (remember to use CUSS). d. Does the data appear to support the alternative hypothesis? Explain your answer. e. Do a hypothesis test to determine whether the water is safe, and use a significance level of a = 0.01. Step 1: State hypotheses in symbols or in words. Step 2: Check conditions for a 1-sample t-test using your work in Part c. Step 3: Use R to find the sample mean and standard deviation to compute the test statistic, then draw the sampling distribution picture (as in #1 Step 3) labeled with the null value and the test statistic and with the area corresponding to the p-value shaded, and find the p-value.
