Acompany that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 40 milligrams. you want to test this claim. during your tests, you find that a random sample of thirty 12-ounce bottles of cola has a mean caffeine content of 42.3 milligrams. assume the population is normally distributed and the population standard deviation is 7.1 milligrams. at alphaequals0.04, can you reject the company's claim

Step-by-step explanation:

Put hypotheses as:

(Two tailed test at 4%)

Since population std deviation is  given we can do Z test.

Test statistic t = mean diff/se =

p value=0.075

Since p >0.04 our alpha, we accept null hypothesis.

At alphaequals0.04, we cannot reject the company's claim

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: x=3 and y=4
