- Last dog Based on the regression output seen in Exer-cise 17, create a 95% confidence interval for the slope of the regression line and interpret your interval in context.• In a political science class, the teacher gives a midterm exam and a final. The association between midterm and final scores is linear. The summary statistics are shown below. Midterm Mean=75, Midterm Standard Deviation=10 Final Mean=75, Final Standard Deviation=10 r=0.8 According to the regression equation, for a student who gets 85 on the midterm (one standard deviation above average) what is the predicted final exam grade? 83 85 70 75Develop the relationship between correlation coefficient and regression coefficient. Mention the applications of correlation and regression.
- Two lines are proposed to describe the relationship between x and y for a particular data set. Shown below are the lines and the sum of squared error for each line. Line1: yˆ = 5+ 4x, Sumofsquarederror= 48.6 Line2: yˆ = 6 + 3.5x, Sumofsquarederror= 40.8 One of these two lines is the regression line. Which line is the regression line?A brokerage firm wants to conduct a study to see If there is a linear relationship between size of an account and the number of trades conducted each year. What would be the most appropriate procedure to use to analyze data to ansiver this question? @ANOVA Ⓒ regression Test of slope for correlation Ⓒ test for a difference of proportions @ chi-square Ⓒ test for difference of meansIf the correlation coefficient between hours spent studying and exam performance is -0.24, then what percent of the variability in the hours spent variable is attributable to the exam performance variable? Round to one decimal place.
- We wish to determine if there is a correlation between the birth weight (in grams) of nine newborn infants and the length of their mothers’ stay (in days) in the hospital. The results of a correlation and regression analysis are indicated in the Excel output below. The mean birth weight of the newborn infants (the independent variable) was 3162.5 grams, and the mean length of their mothers’ stay in the hospital (the dependent variable) was 7 days.

Z score is Use an Excel Function to calculate Z sample size is Show the Formula that you use to calculate it.Define Confidence Intervals for a Regression Coefficient & its properties?Consider a regression that uses X = # of 60 pound bench press repetitions to predict Y = maximum bench press amount in pounds…..for the ith student among a sample of high school athletes. The estimated predicted sample regression is as follows Maxi= 68.91 + .6885Repsi *the ei is left off for simplicity The table below lists the actual data from which the regression above was estimated. For example, a student in the study who trained by doing 12 “60 pound reps” accomplished a maximum bench press amount of 76 pounds.
