- A large candy manufacturer is concerned that the mean weight of their Chunky Chocolate Crisp bar is not greater than 4.3 ounces. It can be assumed that the population standard deviation is .03 ounces based on past experience. A sample of 100 candy bars is selected and the sample mean is 4.34 ounces. Using a level of significance of .10, is there evidence that the population mean weight of the candy bars is greater than 4.3?

- Several factors influence the value obtained for a t statistic. Some factors affect the numerator of the t statistic and others influence the size of estimated standard error in the denominator. For each of the following. indicate whether the factor influences the numerator or denominator of the t statistic and determine whether the effect would be to increase the value of t ( farther from zero) or decrease the value of t ( closer to zero) In each case, assume that all other factors remain the constant. a. Increase the variability of the scores. b. Increase number of scores in the sample. c. Increase the difference between the sample mean and the population mean. - Several factors influence the value obtained for a t statistic.

- The value of the z-score that is obtained for a hypothesis test is influence by several factors. Some factors influence the size of the numerator of the z-score and the factors influence of the standard error in the denominator. For the following, indicate whether the factor influences the numerator or denominator of the z-score and determine whether the effect would be to increase the value of z (farther from zero) or decrease the value of z (closer to zero. In each case, assume that all other component of the z-score remain constant. a. Increase the sample size b. Increase the population standard deviation. c. Increase the difference between the sample mean and the value of the µ specified in the null hypothesis. - 1.
