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

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
