Please help on d and e b.

Develop the least squares estimated regression equation. Enter negative value as negative number.Satisfaction =-.0733 +.9675 Speed (to 4 decimals)d. Provide an interpretation for the slope of the estimated regression equation.The slope of the estimated regression line is approximatelyrating will increase the overall satisfaction rating by approximatelye. Suppose Wells Fargo Investments developed new software to increase their speed of execution rating. If the new software is able to increase their speed ofexecution rating from the current value of 2.4 to the average speed of execution rating for the other 10 brokerage firms that were surveyed, what value wouldyou predict for the overall satisfaction rating?(to 3 decimals)(to 4 decimals). So, a one unitpoints (to 1 decimal).Select your answer - ✓ in the speed of execution The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with discount brokers. As part ofthe survey, members were asked to rate the quality of the speed of execution with their broker as well as provide an overall satisfaction rating for electronictrades. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker summaryscores were computed by calculating a weighted average of the scores provided by each respondent.

Write a short note on regression analysis
Sheila's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if the glucose level is above 140 miligrams per deciliter (mg/dl) one hour after having a sugary drink. Sheila's measured glucose level one hour after the sugary drink varies according to the Normal distribution with μμ = 120 mg/dl and σσ = 10 mg/dl. (a) If a single glucose measurement is made, what is the probability that Sheila is diagnosed as having gestational diabetes?(b) If measurements are made on 5 separate days and the mean result is compared with the criterion 140 mg/dl, what is the probability that Sheila is diagnosed as having gestational diabetes?
Q. 3 A city records indicate that there were 3790 live births in 2012, compared to 3334 live births in 2010. In 2012 there were 10 more neonatal deaths and 17 more infant deaths than in 2010. In 2010 there were 70 neonatal deaths and 80 infant deaths. Calculate neonatal and infant mortality rates (per 1000) for this city for 2010 and 2012. Comment on your calculations.

The file Galton on D2L contains the 928 observations Francis Galton used in 1885 to estimate the relationship between the heights of parents and the heights of their children. The column Children refers to the height (in inches) of a child, and the column Mid-Parents refers to the average height (in inches) of the mother and father of that child. You can download this file into Excel and Minitab. a. Calculate the regression Height of Children = a +b (Height of Mid-Parents). b. Calculate the average for Height of Children, and calculate the average Height of Mid-Parents. c. Create a new variable in Minitab which is the Height of Children measured in terms of deviations from its mean. Call this new variable y. Also, create a new variable in Minitab with is the Height of Mid-Parents measured in terms of deviations from its mean. Call this new variable x. Calculate the regression y = a + bx. You can create the new y and x variables in Excel of Minitab, whichever you find more convenient.…
