Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.5 parts/million (ppm). A researcher believes that the current ozone level is not at the normal level. The mean of 13 samples is 6.0 ppm with a standard deviation of 0.9 Does the data support the claim at the 0.1level? Assume the population distribution is approximately normal.
Step 1 of 3 : State the null and alternative hypotheses.
Step 2 of 3: find the p value for the hypothesis test
Step 3 of 3 : Make the decision to reject or fail to reject the null hypothesis.

Our environment is very sensitive to the amount of ozone in the
upper atmosphere. The level of ozone normally found is 5.5
parts/million (ppm). A researcher believes that the current ozone
level is at an excess level. The mean of 6 samples is 5.9 ppm with
a variance of 0.49. Does the data support the claim at the 0.05
level? Assume the population distribution is approximately
normal.
