Question

Matched pairs samples: Use the matched pairs sample to answer the following questions. Assume all requirements have been met.

In an effort to reduce water use during a drought 10 families had their water use measured before and after viewing a video on the negative effect of wasting water. Measurements are in gallons per day.

Before	120	95	84	90	111	94	99	96	75	51
After	110	98	89	85	105	90	95	96	74	47

Test the claim that the video was effective in reducing water use.
Is this a left, right, or two tailed test?
What is the P-value?
Will the null hypothesis be rejected? Use a 5% level of significance.
Was the video effective in reducing water use? Explain in 1 - 2 complete sentences.
Construct the 90% confidence interval for the difference before and after viewing the video.
