Answer:
And the confidence interval for the difference is between:
Step-by-step explanation:
We have the following info given:
sample mean for medium Pizzas from Prim's
sample mean for medium Pizzas from Pizza Place
sample deviation for Prim's
sample deviation for Pizza Palca
sample size selected for each case
The confidence interval for the difference of means is given by:
And for the 95% confidence we need a significance level of and
, the degrees of freedom are given by:
And the critical value would be
And replacing we got:
And the confidence interval for the difference is between:
I 11 x - 22 I > 22
∴ 11x-22 > 22 OR (11x -22) < -22
∴ 11 x > 44 :::::::: 11x - 22 < -22
x > 4 :::::::: x < 0
∴ x ∈ ( -∞ , 0 ) ∪ ( 4 , ∞)
∴ The correct choice is number 1
The solution is attached in the figure
∴ 11x-22 > 22 OR (11x -22) < -22
∴ 11 x > 44 :::::::: 11x - 22 < -22
x > 4 :::::::: x < 0
∴ x ∈ ( -∞ , 0 ) ∪ ( 4 , ∞)
∴ The correct choice is number 1
The solution is attached in the figure
