Using the numerical data for your team project, conduct a two sample, two-tailed hypothesis test for the mean, with a 0.05 level of significance. Find and interpret each step.

H0:

H1:

Test statistic =

Critical value =

p-value =

Reject the null hypothesis or do not reject the null hypothesis?

What does this mean?

For example:

H0: ƒÊX = ƒÊY

The mean (average) gas price in city X equals the mean (average) gas price in city Y during January 2012.

H1: ƒÊX ‚ ƒÊY

The mean (average) gas price in city X does not equal the mean (average) gas price in city Y during January 2012.
