Assume that 37.5

37.5% of people have sleepwalked. Assume that in a random sample of 1524

1524 adults, 616

616 have sleepwalked.

a. Assuming that the rate of 37.5

37.5% iscorrect, find the probability that 616

616 or more of the 1524

1524 adults have sleepwalked.

b. Is that result of 616

616 or more significantlyhigh?

c. What does the result suggest about the rate of 37.5

37.5%?

a. Assuming that the rate of 37.5

37.5% iscorrect, the probability that 616

616 or more of the 1524

1524 adults have sleepwalked is

nothing

.

(Round to four decimal places asneeded.)

b. Is that result of 616

616 or more significantlyhigh?

Yes,

No,

because the probability of this event is

greater

less

than the probability cutoff that corresponds to a significantevent, which is

0.5.

0.95.

0.05.

c. What does the result suggest about the rate of 37.5

37.5%?

A.

Since the result of 616

616 adults that have sleepwalked is not

isnot significantlyhigh, it is not

isnot strong evidence against the assumed rate of 37.5

37.5%.

B.

Since the result of 616

616 adults that have sleepwalked is

is significantlyhigh, it is

is strong evidence supporting the assumed rate of 37.5

37.5%.

C.

The results do not indicate anything about thescientist's assumption.

D.

Since the result of 616

616 adults that have sleepwalked is

is significantlyhigh, it is not

isnot strong evidence against the assumed rate of 37.5

37.5%.

E.

Since the result of 616

616 adults that have sleepwalked is not

isnot significantlyhigh, it is

is strong evidence against the assumed rate of 37.5

37.5%.

F.

Since the result of 616

616 adults that have sleepwalked is

is significantlyhigh, it is

is strong evidence against the assumed rate of 37.5

37.5%.
