An advertising company has developed a new ad for one of the national car manufacturing companies. the ad agency is interested in testing whether the proportion of favorable response to the ad is the same between male adults versus female adults. it plans on conducting the test using an alpha level equal to 0.05. a sample of 100 adults of each gender will be used in the study. each person will be asked to view the ad and indicate whether they find the ad to be "pleasing" or not. given this information, what is the critical value?

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
