# Question

Employee suggestions can provide useful and insightful ideas for management. Some companies solicit and receive employee suggestions more than others, and company culture influences the use of employee suggestions. Suppose a study is conducted to determine whether there is a significant difference in mean number of suggestions per year per employee between the Canon Corporation and the Pioneer Electronic Corporation. The study shows that the average number of suggestions per year per employee is 1.3 at Canon and 1.0 at Pioneer. Suppose these figures were obtained from random samples of 36 and 45 employees, respectively. If the population standard deviations of suggestions per employee are 0.7 and 0.4 for Canon and Pioneer, respectively, is there a significant difference in the population means? Use α = .05.
