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 " .

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
