A scientist estimates that the mean nitrogen dioxide level in in Calgary is greater than 32 parts per billion. You want to test this estimate. To do so, you determine the nitrogen dioxide levels for 34 Randomly selected days. The results (in parts per billion) are shown in the table. Can you support the scientists claim

State the Null and the Alternative Hypothesis Null H0; =32 Alternative Ha: >32

Where will be the randomization distribution be centered? Around the null hypothesis at 32.

Is this a right tail test, Left tail or two tail tests? Two tail test

Give the value and the notation for the sample statistics?

Use the StatKey to generate a randomization distribution, find the p-value 0.077+0.077=

p-value = 0.154

Compare p-value to Alpha

Decide whether to Reject / Do Not Reject the Null Hypothesis

State the conclusion in context
