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 at an insufficient level, The mean of 12 samples is 6.9 ppm with a standard deviation of 0.9, Does the data support the claim at the 0.05 level? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses.
