Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.1 parts/million (ppm). A researcher believes that the current ozone level is not at the normal level. The mean of 26 samples is 6.6 ppm with a standard deviation of 1.0. Does the data support the claim at the 0.05 level? Assume the population distribution is approximately normal.

Step 5 of 5: Make the decision to reject or fail to reject the null hypothesis.
