Q P.15: According to a theater, about 8% of all people who buy a ticket to a performance arrive late. Find the mea
and standard deviation of the number of people who are late if 300 tickets have been sold.
A
The mean is µ
300 · 0. 08 = 24. The standard deviation is o = v300 · 0. 08 · 0. 92 z 4. 70.
В
The mean is u = V300 · 0. 08 · 0. 92 2 4. 70. The standard deviation is o = 300 · 0. 08 = 24.
The mean is µ
300 · 0. 08 · 0. 92 = 22. 08. The standard deviation is o =
300 · 0. 92 = 276.
The mean is u = 300 · 0. 92 = 276. The standard deviation is o = 300 · 0. 08 · 0.92 = 22. 08.

E
The mean is u
300 · 0. 08 = 24. The standard deviation is o =
300 · 0. 08 · 0. 92 = 22. 08.
