fredd [130]

Answer: 0.9088

Step-by-step explanation:

Given : $\mu=0.30$

$\sigma=0.045$

Let x be a random available that represents the proportion of students that reads below grade level .

Using $z=\dfrac{x-\mu}{\sigma$ , for x= 0.36 , we have

$z=\dfrac{0.36-0.30}{0.045}=1.33333$

Using standard normal z-value table,

P-value $= P($

$P(z$ [Rounded yo the nearest 4 decimal places.]

Hence, the probability that a second sample would be selected with a proportion less than 0.36 = 0.9088
