Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 6.0 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 21 samples is 6.3 ppm with a standard deviation of 1.1. Does the data support the claim at the 0.025 level? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses.
