Researchers are interested in predicting the height of a child based on the heights of their motherand father. Data were collected, which included height of the child (height ), height of the mother (mothersheight ), and height of the father ( fathersheight ). The initial analysis used the heights of theparents to predict the height of the child (all units are inches). The results of the analysis, a multipleregression, are presented below..regress height mothersheight fathersheightSourceModelResidualTotalheightmothersheightfathersheight_consSSdf208.008457314.295372 37522.3038292 104.0042288.49446952MS39 13.3924059Coef.

A regression analysis is a statistical package that researchers use to determine a whether a linear relationship exists between the dependent variable and independent variables. If True, discuss. If False, discuss
We expect a car's highway gas mileage to be related to its city gas mileage (in miles per gallon, mpg). Data for all 1259 vehicles in the government's 2019 Fuel Economy Guide give the regression line highway mpg = 8.720 + (0.914x city mpg) for predicting highway mileage from city mileage. 1 O Macmillan Learning (b) What is the intercept? Give your answer to three decimal places. intercept: Why is the value of the intercept not statistically meaningful? The value of the intercept is an average value calculated from a sample. The value of the intercept represents the predicted highway mileage for city gas mileage of 0 mpg, and such a prediction would be invalid since 0 is outside the range of the data. The value of the intercept represents the predicted highway mileage for slope 0. O The value of the intercept represents the predicted city mileage for highway gas mileage of 0 mpg, and such a car does not exist. mpg
