Get college assignment help at uniessay writers Perform a regression analysis on the data using MS Excel. Observations are taken on net revenue from sales of Hughes, HNS, and satellite services to see if offering rebates is beneficial for the organization. Dealers don’t get rebates, but customers get a $100 mail in rebate and to keep customers when they call into Hughes to cancel the services, HNS will offer another $50 credit to the account. The regression model is Y = net revenue, X1 = shipping cost (dollars per unit), X2 = purchase pole mounts, X3 = dealers cost per equipment including dish, radio, and modem, X4 = Ads, X5 = installation. Regression: Y = X1 X2 X3 X4 X5… Predictor Coefficient Shipping Cost 60.00 Pole Mounts 65.00 Equipment 200.00 Ads 40.00 Rebate 100.00

“A geologist is using seismographs to test for oil. It is found that if oil is present, the test gives a positive result 75% of the time, and if oil is not present, the test gives a positive result 8% of the time. Oil is actually present in 2% of the cases tested. If the test shows positive, what is the probability that oil is present? ”

Test at = 0.05. 3. Evaluate whether the assumption needed to conduct the tests in (1) and (2) has been seriously violated.
An important quality characteristic used by the manufacturer of Boston and
An important quality characteristic used by the manufacturer of Boston and Vermont asphalt shingles is the amount of moisture the shingles contain when they are packaged. Customers may feel that they have purchased a product lacking in quality if they find moisture and wet shingles inside the packaging. In some cases, excessive moisture can cause the granules attached to the shingle for texture and coloring purposes to fall off the shingle, resulting in appearance problems. To monitor the amount of moisture present, the company conducts moisture tests. A shingle is weighed and then dried. The shingle is them reweighed and based on the amount of moisture taken out of the product; the pounds of moisture per 100 square feet are calculated. The company would like to show that the average moisture content is less than 0.35 pounds per 100 square feet. The data is below; it includes 36 measurements (in pounds per 100 square feet) for the Boston shingles and 31 for the Vermont Shingles.

The manufacturer of Boston and Vermont asphalt shingles knows that product
The manufacturer of Boston and Vermont asphalt shingles knows that product weight is a major factor in the customer’s perception of quality. Moreover, the weight represents the amount of raw materials being used and is therefore very important to the company from a cost standpoint. The last stage of the assembly line packages the shingles before they are placed on wooden pallets. Once a pallet is full (a pallet for most brands holds 16 squares of shingles), it is weighed, and the measurement is recorded. The data file (Pallet) contains the weight (in pounds) from a sample of 368 pallets of Boston shingles and 330 pallets of Vermont shingles. Completely analyze the differences in the weights of the Boston and Vermont shingles, using α = 0.05.

Moreover, the weight represents the amount of raw materials being used and is therefore very important to the company from a cost standpoint. The last stage of the assembly line packages the shingles before they are placed on wooden pallets. Once a pallet is full (a pallet for most brands holds 16 squares of shingles), it is weighed, and the measurement is recorded. The data file (Pallet) contains the weight (in pounds) from a sample of 368 pallets of Boston shingles and 330 pallets of Vermont shingles. Completely analyze the differences in the weights of the Boston and Vermont shingles, using α = 0.05.

Unoccupied seats on flights cause airlines to lose revenue. It is
Unoccupied seats on flights cause airlines to lose revenue. It is known from past experience that the standard deviation is 3.2 unoccupied seats. Suppose a large airline wants to estimate the average number of unoccupied seats per flight. Records of 50 flights were randomly selected from the files, and the number of unoccupied seats was noted for each of the sampled flights. The sample mean was 8.4 seats. Suppose a 90% interval estimate for the average number of unoccupied seats was calculated? How large should the sample have been if a margin of error of 0.25 seats was desired?
