The weight of discarded plastic from a sample of 62 households is xbar = 1.911 lbs and s = 1.065 lbs. a. Use a 0.05 significance level to test the claim that the mean weight of discarded plastics from the population of households is greater than 1.8 lbs.
b. Now assume that the population standard deviation sigma is known to be 1.065 lbs. Use a= 0.05 significance level to test the claim that the mean weight of discarded plastics from the population of households is greater than 1.8 lbs.

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
