A) Rejecting a null hypothesis provides a stronger conclusion than failing to reject a null hypothesis. Therefore, place what we are trying to demonstrate in the alternative hypothesis. Assume that the data follow a normal distribution. b) 1) the parameter of interest is the mean weld strength, µ. 05 < p − value < 010 . 8) There is some modest evidence to support the claim that the weld strength exceeds 150 psi. 05, we would not reject the null hypothesis, thus the claim would not be supported.

91, ∞) The lower tolerance bound is of interest if we want to make sure the wall thickness is at least a certain value so that the bottle will not break. 5. 5  = 23 As the standard deviation decreases, with all other values held constant, the sample size necessary to maintain the acceptable level of confidence and the length of the interval, decreases. ) 99% prediction interval on the coefficient of restitution for the next baseball that will be tested. )The confidence interval in part (b) describes the confidence interval on the population mean and we may interpret this to mean that 99% of such intervals will cover the population mean.
