Answer:
20 pints per hour
Step-by-step explanation:
60/6 = 10
10 x 4 = 40
40 pints/hour in the morning
60/3 = 20
20 x 1 =20
20 pints/hour in the afternoon
40 - 20 = 20
20 pint/hour difference
Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.
