Answer: A pint is equal to 2 cups (example: a large glass of milk!) When measuring many cups of liquid all put together we might want to use quarts. A quart (qt) is the same thing as 4 cups or 2 pints.

A customer service phone line claims that the wait times before a call is answered by a service representative is less than 3.3

8_murik_8 [283]

Answer:

Step-by-step explanation:

Let x be the wait times before a call is answered in phone calls.

The claim is x bar <3.3 minutes

Sample size n =62

Sample mean - x bar = 3.24 minutes

Population std dev = $\sigma = 0.40 minutes\\$

Since population std dev is known and also sample size is sufficiently large, we can use Z test.

$H_0: x bar = 3.3\\H_a: x bar$

(one tailed test)

Mean difference = 3.24-3.3 = -0.06 min

Std error of sample = $\frac{\sigma}{\sqrt{n} } =\frac{0.40}{\sqrt{62} } \\=0.0508$

Z = tset statistic = $\frac{-006}{0.0508} \\\\=-1.18$

p value = 0.119

Since p value > alpha, we accept null hypothesis.

There is no evidence to support the claim at alpha = 0.08
