Answer:
p=1
Step-by-step explanation:
Given that a day care program has an average daily expense of $75.00. The standard deviation is $5.00.
Sample size = 64
Std error of sample = [tex]\frac{5}{\sqrt{64} } \\=0.625[/tex]
Thus sample mean will follow normal with
(75, 0.625)
Required probability
=[tex]P(70<\bar x <80)\\\\= P(|z|<16)\\=1[/tex]
It is almost a certain event with p =1
