a. Do a 95% hypothesis test to test if:
(H0) the mean CONTROL level is greater than 0.89 vs. (Ha) he mean CONTROL level is less than 0.89.
Report the p-value:
Reject Null hypothesis at the 95% level of confidence?
yes OR no
b. Do a 95% hypothesis test to test if:
(H0) the mean of the CONTROL is equal to the mean of the TREATMENT vs. (Ha) the mean of the CONTROL is not equal to the mean of the TREATMENT.
Report the p-value:
Reject Null hypothesis at the 95% level of confidence?
yes OR no
c. Do a 95% hypothesis test to test if:
(H0) the mean of the CONTROL is less than the mean of the TREATMENT vs. (Ha) the mean of the CONTROL is greater than the mean of the TREATMENT (Ha).
Report the p-value: .

We wish to study the effect that the size of various U.S.
cities have over ozone concentrations. The size of the populations
correspond to the last census (in millions of inhabitants), and the
average quantity of ozone per hour was determined in (parts per
thousand millions);

variables are linearly related.

Michael measures the volume of several raindrops at Rainyville
as 0.6 ml, 0.65 ml, 0.7 ml, 0.75 ml, 0.8 ml and 0.85 ml; and comes
to believe that the raindrops at Rainyville are significantly
larger than the national average of 0.65ml at the 5% level.
If Michael performs the appropriate statistical test, what will
be his conclusion?
1. fail to reject the null hypothesis or 2. reject the null
hypotheses
