Assume that 25% of people have sleepwalked. Assume that in a random sample of 1470 adults, 377 have sleepwalked.
a. Assuming that the rate of 25% is correct, find the probability that 377 or more of the 1470 adults have sleepwalked.
b. Is that result of 377 or more significantly high?
c. What does the result suggest about the rate of 25%?

good luck!

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
