Does Table 1 represent a linear function? If so, finda linear equation that models the data.

Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.

The following equation is the result of performing a multiple regression analysis: Job performance = 10 + (5*job knowledge) + (0.7* conscientiousness), where job knowledge is measured on a scale of 0-5 and conscientiousness is measured on a scale of 0 to 100. Which of the following conclusions is correct? !! O If a person scored 5 on job knowledge and 100 on conscientiousness he or she would have the maximum predictive score possible If a person scored 0 on both job knowledge and conscientiousness, his or her predictive score is 0 ONeither job knowledge nor conscientiousness predicts performance O Conscientiousness is less important than job knowledge. Question 3! For a measuring tool to be usefulitmus be

What is meant by the slope of the regression line?

Explain the first step in the written development of a regression model?

We want to predict the percentage weight loss for 2011 participants, based on 2010 data. If we construct a simple linear regression model, predicting percentage weight loss as a function of starting weight, what are the values of y-intercept ("a") and regression coefficient ("b"), rounded to one and two decimal places?0.4 and 0.110.3 and 0.010.4 and 0.020.3 and 0.07According to the regression model calculated above, what is the value of "r", rounded to one decimal place?00.200.300.400.500.1 In the above question, what does "r" represent?Spearman's correlation coefficientPearson's correlation coefficientThe variability of the dependent variable explained by the independent variableThe variability of the independent variable explained by the dependent variable If we were to add "age" as an additional independent variable to the calculated regression model, we'd have a multiple linear regression equation. For such a model, would the calculated "R" be :- equal to or greater than the "r"…

Suppose that a researcher studying the weight of female college athletes wants to predict the weights based on height, measured in inches, and the percentage of body fat of an athlete. The researcher calculates the regression equation as (weight) = 3.544*(height) + 1.064*(percent body fat) - 87.076. If a female athlete is 64 inches tall and has a 21 percentage of body fat, what is her expected weight?   Question 24 options:   1)  55.444   2)  We do not know the observations in the data set, so we cannot answer that question.   3)  162.084   4)  249.16   5)  336.236
