## Document Summary

There is enough evidence to infer that the mean weight of new product is different from 180 lbs. We estimate with 95% confidence the mean weight of new products lies between 178. 0667lbs and. There is not enough evidence to infer that the standard deviation will not exceed. Sample size to estimate p , (if p is unknown, take . 5) 1%: only if a is more than 8% smaller than b ( v ) Conclusion: reject h0, there is sufficient evidence the mean gpa now exceed the mean 10 years ago. 2. 85 -2. 33 or p-value =p(z< 2. 85) = . 5 . 4978 = . 0022. Conclusion: reject h0, there is enough evidence to conclude that management should adopt process a.
