Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.3 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 9 samples is 5.6 ppm with a standard deviation of 0.6. Assume the population is normally distributed. A level of significance of 0.05
will be used. Find the value of the test statistic. Round your answer to three decimal places.
Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.6 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 14 samples is 4.9 ppm with a variance of 1.2 Does the data support the claim at the 0.01 level? Assume the population distribution is approximately normal.
