In studying his campaign plans, Mr. Singleton wishes to estimate the difference between men's and women's views regarding his appeal as a candidate. He asks his campaign manager to take two random independent samples and find the 80%80% confidence interval for the difference. A random sample of 508508 male voters and 605605 female voters was taken. 108108 men and 193193 women favored Mr. Singleton as a candidate. Find this confidence interval. Step 2 of 4 : Find the critical value that should be used in constructing the confidence interval.
A week before delivery, the customer indicated that it could only take 600 of the 800 items. Because of the long-standing relationship MFMI decided to accept this revised arrangement and mandate the sales team to sell the remaining 200 items in the market for at least $7000 per item. At the end of the period the sales team reported to management that they have identified buyers who were willing to purchase the 200 items at a rate of $6100 per item and at the management’s preferred price only 140 of the 200 would be sold. Assumed that the sale team is correct, determine the quantity that would be sold if management agreed to a 5% reduction in their original price. Based on your response to part (ii), describe the type of demand for this item. 2. Assumes that the firm retools, would it make an accounting profit if the additional 200 units relating to this…
