please give some detailed solution and please do not copy other's work,thanks!! According to a union agreement, the mean income for all senior-level assembly-line workers in a large company is $500 per week. A representative of a women's group decides to analyse whether the mean income for female employees matches this norm. For a random sample of 50 female employees, the mean is $410 and the SD is $90. Test with a-0.05, whether the mean income of female employees differs from $500 per week. What is the probability of the Type II error in this case?

a. Use a = 0.10 to test for a statistically significantly difference between the population means for first- and fourth-round scores. What is the p-value? t-value (to 3 decimals) Degrees of freedom p-value is greater than 0.20 What is your conclusion? There is no significant difference between the mean scores for the first and final rounds. b. What is the point estimate of the difference between the two population means? (to 2 decimals) For which round is the population mean score lower? First round c. What is the margin of error for a 90% confidence interval estimate for the difference between the population means? (to 3 decimals) Could this confidence interval have been used to test the hypothesis in part (a)? Yes Explain. Use the point of the difference between the two population means and add and subtract this MOE. If zero is in the interval the difference is not statistically significant. If zero is not in the interval the difference is statistically significant.
