Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.05 to test for a difference between the weights of discarded paper (in pounds) and weights of discarded plastic (in pounds).

Identify the test statistic:
Identify the P Value:
Since the P-value is (greater,less than) the significance level, (fail to reject, reject) the null hypothesis. There (is not, is) sufficient evidence to support the claim that there is a difference between the weights of discarded paper and discarded plastic.
Transcribed Image Text:Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a
distribution that is approximately normal. Use a significance level of 0.05 to test for a difference between the weights of discarded paper (in
pounds) and weights of discarded plastic (in pounds).
