Consider the trash bag problem. Suppose that an independent laboratory has tested trash bags and has found that no 30-gallon bags that are currently on the market have a mean breaking strength of 50 pounds or more. On the basis of these results, the producer of the new, improved trash bag feels sure that its 30-gallon bag will be the strongest such bag on the market if the new trash bag’s mean breaking strength can be shown to be at least 50 pounds. The mean of the sample of 37 trash bag breaking strengths in Table 1.9 is x¯x¯ = 50.560. If we let µ denote the mean of the breaking strengths of all possible trash bags of the new type and assume that σ equals 1.67:
(a) Calculate 95 percent and 99 percent
confidence intervals for µ. (Round your answers to
3 decimal places.)
95 percent confidence intervals for µ is | [ , ]. |
99 percent confidence intervals for µ is |

Use the six-step process and assumption format to complete the following: Problem Definition/Research Objective: A manufacturer wishes to advertise a new environmentally friendly trash bag on a major TV Network. The manufactures wished to claim that bags strength has been significantly increased compared to past 30-gallon bags. The network wants significance statistical evidence regarding the claim that the new bag is stronger. Agreed testing will measure the variable of strength in terms of poundage of content placed into the bag...

A corporation is considering a new issue of convertible bonds. Management believes that the offer terms will be found attractive by 20% of all its current stockholders. Suppose that the belief is correct. A random sample of 130 stockholders is taken. What is the probability that the sample proportion of those stockholders that find the terms attractive will be between .18 and .23? 1. In a small town, households recycle on average 30% of their waste. The new recycling committee...
