For a large supermarket chain in a particular state, a women's group claimed that female employees were passed over for management training in favor of their male colleagues. The company denied this claim, saying it picked the employees from the eligible pool at random to receive this training. Statewide, the large pool of more than 1000 eligible employees who can be tapped for management training is 45% female and 55% male. Since this program began, 40 of the 65 employees chosen for management training were male and 25 were female. The accompanying table shows the results of using MINITAB to do a large-sample analysis. Refer to the 95% confidence interval shown in the MINITAB output. What are the plausible values for the probability of a female to be selected for training? Is this in accordance with the decision that was made for a 0.05 significance level? Explain. Click the icon to view the MINITAB output.
