A study was conducted on 64 female college athletes. The researcher collected data on a number of variables including percent bo
dy fat, total body weight, lean body mass, and age of athlete. The researcher wondered if total body weight (TBW), lean body mass (LBM), and/or age are significant predictors of % body fat. All conditions have been checked and are met and no transformations were needed. The partial technology output from the multiple regression analysis is given below. How many degrees of freedom does the F-statistic have in this problem?

Answer:
Hello please your question is in-complete attached is the complete question
degree of freedom = -62.90 ( e )
Step-by-step explanation:
The formula for calculating the F-statistic/test statistic is
test - statistic = Coef ( LBW) / SE Coef ( LBW )
= -0.72399 / 0.01151
= - 62.90
the degree of freedom the F-statistic has = -62.90
F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models

Answer:
The first 3 terms in the expansion of , in ascending power of x are,
coefficient of in the expansion of
= (240 - 192) = 48
Step-by-step explanation:
=
= + terms involving higher powers of x
= + terms involving higher powers of x
so, the first 3 terms in the expansion of , in ascending power of x are,
Again,
=
Now, by inspection,
the term comes from k =5 and k = 6
for k = 5, the coefficient of is ,
= -192
for k = 6 , the coefficient of is,
= 240
so, coefficient of in the final expression = (240 - 192) = 48
