ryzh [129]

Answer:

The z statistic is 0.23.

Step-by-step explanation:

Test statistic (z) = (sample mean - population mean) ÷ sd/√n

sample mean = 104 mg

population mean (mu) = 100 mg

sd = 55 mg

n = 10

z = (104 - 100) ÷ 55/√10 = 4 ÷ 17.393 = 0.23

Suppose that the probabilities that an answer can be found on Google is .95, on Answers is .92, and on both Web sites is .874. A
Assoli18 [71]

Answer:

The correct option is

a) Yes, because (0.95)(0.92) = 0.874

Step-by-step explanation:

An event is independent if the following condition is satisfied

P(A\bigcap B)= P(A)P(B)

Therefore, since the the probability that the answer can be found in Google = 0.95 and the probability that the answer can be found in Answers = 0.92

The probability that the answer can be found on both websites,  

P(A\bigcap B) = 0.874

We check, P(A) × P(B) = 0.95×0.92 = 0.874 = P(A\bigcap B) = 0.874

Therefore, the possibilities of finding the event on the two websites is independent.
