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 excess level. The mean of 26 samples is 7.4 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. Answer Ho: H₂: Keypad Keyboard Shortcuts Tables
