Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is6.4 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of8 samples is5.9 ppm with a variance of0.49. Assume the population is normally distributed. A level of significance of0.02 will be used. Make the decision to reject or fail to reject the null hypothesis.
