Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.8 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 26 samples is 5.9 ppm with a standard deviation of 0.6. Does the data support the claim at the 0.01 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

Expert Solution
Step 1: Determine the given variables.

The question is about hypothesis testing.

Given :

Population mean level of ozone ( mu ) = 5.8 ppm

Selected no. of samples ( n ) = 26

Sample mean level of ozone ( x with bar on top ) = 5.9 ppm

Sample standard deviation of ozone level ( s ) = 0.6 ppm


To find :

1 ) Hypotheses for the test.

2 ) Test the given claim.
