Answer:

x = 91

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral are supplementary, that is

∠ A + ∠ C = 180, thus

x + 89 = 180 ( subtract 89 from both sides )

x = 91

A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 40 milligrams. You want t

ziro4ka [17]

Answer:

Step-by-step explanation:

Put hypotheses as:

$H_0: mu =40 mg\\H_a: mu \neq 40 mg.$

(Two tailed test at 4%)

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

$Sample size n =30\\Sample mean = 42.3 mg\\Mean diff = 2.3 mg\\Std error of sample = \frac{7.1}{\sqrt{30} } =1.296$

Test statistic t = mean diff/se = $\frac{2.3}{1.296} =1.775$

p value=0.075

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

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