Question

A study was conducted on 64 female college athletes. The researcher collected data on a number o variables including percent body at total body weight, height, and age of athlete. The researcher wondered if % body fat %BF height HGT), and/or age are significant predictors of total body weight. All conditions have been checked and are met and no transformations were needed. The technology output from the multiple regression analysis is given below When testing Ho.p1-0, where 1 is the coefficient or 9 body fat, what test statistic is used and how many degrees of freedom does that test statistic have? Click the icon to view the multiple regression analysis Choose the correct answer below. O A· t-statistic with 60 degrees of freedom OB statisic with 62 degrees of treem ° C. F-statistic with 3 numerator and 60 denominator degrees of freedom 0 D. t-statistic with 3 numerator and 60 denominator degrees of freedom E. F-statistic with 60 degrees of freedom

Explanation / Answer

For this regression model we have total 64 observation.

We have three predictor variable therefore for testing single regression coefficient we used t - test statistic with (64 - 4) degrees of freedom.

Therefore we ues t statistic with 60 degrees of freedom.

Therefore option A is correct.
