The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.4, 15.8, 15.4, 15.1, 15.8, 15.9, 15.8, 15.7 when constructing a 98% confidence interval for the mean amount of juice in all such bottles the degree of freedom used in this construction is

The answer is: " 7 " .

Explanation:

degrees of freedom (df) = n - 1 ;

n = sample size = 8 ;

n - 1 = 8 - 1 = 7 .

The answer is: " 7 " .

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
