Find the critical value and identify the rejection region 

Identify the standardized test statistic use technology 

decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim 

A scientist estimates that the mean nitrogen dioxide level in a city is greater
than 33 parts per billion. To test this estimate, you determine the nitrogen
dioxide levels for 31 randomly selected days. The results (in parts per billion)
are listed to the right. Assume that the population standard deviation is 7. At
a=0.14, can you support the scientist's estimate? Complete parts (a)
through (e).
A. Ho: μ-33 (claim)
H₂:μ> 33
(a) Write the claim mathematically and identify Ho and H₂. Choose from the following.
_ B. Họ H≥33 (claim)
Ha:μ<33
XD. Ho: p=33
