A local Alcoholics Anonymous chapter normally holds meeting at 5:45. Some

similarly sized chapters think 6:45 will increase attendance. They take a random of

ten chapters with bimonthly meeting starting times of 5:45 and eleven with 6:45

bimonthly meetings from the Fall of last year. Is there a difference in attendance?

5:45 : 90, 80, 70, 80, 70, 70, 70, 70, 80, 70

6:45 : 80, 60, 70, 90, 60, 70, 60, 50, 50, 70

• Provide the null and alternative hypotheses in formal and plain language for appropriate two-tailed test (viz., dependent or independent) at the 0.05 significance level
• Do the math and reject/accept null at a=.05. State your critical t value.
• Explain the results in plain language.
• Calculate the 95% confidence interval for the difference in means and state both formally and in plain language if appropriate.

This whole process is confusing for me - I don't even know where to start
