Answer:

And we can use the normal standard distribution table and we got:

Step-by-step explanation:
For this case we know the following info given:
represent the population proportion
represent the sample size selected
We want to find the following proportion:

For this case we can use the normal approximation since we have the following conditions:
i) np = 622*0.14 = 87.08>10
ii) n(1-p) = 622*(1-0.14) =534.92>10
The distribution for the sample proportion would be given by:

The mean is given by:

And the deviation:

We can use the z score formula given by:

And replacing we got:

And we can use the normal standard distribution table and we got:

Answer:
each shirt cost $12
Step-by-step explanation:
Volume of square pyramid = (base area) * h/3
= (157 * 157) * 95/3
=24,649 * 95/3
=780,551.67 m3
Btw [*] means multiply
