coupons.
And Mrs. Fowler has
coupons.
Part (a)
How many free pizzas can Mrs. Fowler get if she has
coupons?
We will divide total number of coupons
by
coupons.

When we divide we get quotient as
, with a remainder of
. So, Mrs. Fowler will get
free pizza.
Now, part (b)
If Mrs. Fowler adds two more coupons that will turn remainder
into
.
So, she can have next pizza.
The probability that a random sample of 12 second grade students results in a mean reading rate of more than 95 words per minute is 0.4582.
Given that the population mean,
= 90 wpm
The standard deviation of the population ,
= 10
Sample size, n = 12
Sample mean,
= 95
The reading rate of students follows the normal distribution.
Let z = 
= 
= 1.732
Probability that the mean reading exceeds 95 wpm = P(
>95)
= P(z>1.732)
= 1- P(z<1.732)
= 0.4582
[The value 0.4582 found from the area under the normal curve using tables].
