- Respiratory Rate Researchers have found that the 95 th percentile the value at which 95% of the data are at or below for respiratory rates in breath per minute during the first 3 years of infancy are given by y=101.82411-0.0125995x+0.00013401x2 for awake infants and y=101.72858-0.0139928x+0.00017646x2 for sleeping infants, where x is the age in months. Source: Pediatrics. a. What is the domain for each function? b. For each respiratory rate, is the rate decreasing or increasing over the first 3 years of life? Hint: Is the graph of the quadratic in the exponent opening upward or downward? Where is the vertex? c. Verify your answer to part b using a graphing calculator. d. For a 1- year-old infant in the 95 th percentile, how much higher is the walking respiratory rate then the sleeping respiratory rate? e. f.21) Below is some of the regression output from a simple regression of the number of wins for a major league baseball team and the size amount of money the team is paying its players (expressed in millions of $'s) *Please fill in the table and show scratchwork*You want to look at an ANOVA table of a regression in which a dependent variable is predicted using an intercept and one slope coefficient. Unfortunately, as you want to look at the table, you knock over your coffee mug which smudges out some of the numbers.

- how to plot the estimated regression line on the scatter diagram in letter c and how to solve for letter d with graphAccountants at the Tucsan firm Larry Youdleman cpas believed that several traveling executives were submitting unusually high travel vouchers wehn they returned from business trips. First they took a sample of 200 vouchers submitted from the past year. Then they developed the following multiple regression equation relating expected travel cost to number of days on the road (X1) and distance traveled (X2) in miles ^y= $95.00+$50.50X1+$0.40X2 The coefficient of correlation for the model is 0.72 a) If Donna Battista returns from a 300 mile trip that took her out of tow for 6 days the expected amount that she should claim as expense = $518 b) after the 300 mile and 6 day trip Battista submitted a reimbursement request dfor $785 which is different than predicted value. The accountant should question the voucher as the request is much higher than expected c) Additional variables that could be included in the model are (select that choice that has all the factors you would consider)…in multiple regression analysis, a residual is the difference between the value of a dependent variable and its corresponding independents variable value? True or false?
- In regression, what do residuals tell us? The amount of error between the predicted y-values and the actual y-values. Residuals tell us how close the predicted values are to the average of the y variable at each value of the x-variable. How much error there was in predicting the x-variable from the actual value for the x-variable. How much the predicted values for the y- variable are different from the pointof-averages.To determine if the listing price of a house influences the selling price; a financial analyst sampled fifty houses and collected data on sale price, Y,(in $'000) and listed price,X,(in$'000) and fitted a regression model to the data.
