The time needed to complete a final examination in a particular college course is normally distributed with a mean of 79 minutes

bagirrra123 [75]

Answer: a) 0.0088

b) 0.2997

c) 5

Step-by-step explanation:

Given : Mean : $\mu = 79$ minutes

Standard deviation : $\sigma = 8$ minutes

The formula for z-score :

$z=\dfrac{x-\mu}{\sigma}$

a) For x = 60 minutes

$z=\dfrac{60-79}{8}=-2.375$

The p-value = $P(z\leq-2.375)=0.0087745\approx0.0088$

b) For x = 75 minutes

$z=\dfrac{75-79}{8}=-0.5$

The p-value = $P(60$

$=P(-0.5)-P(-2.375)=0.3085-0.0088=0.2997$

c) For x = 90 minutes

$z=\dfrac{90-79}{8}=1.375$

The p-value = $P(z>1.375)=1-P(z$

$=1-0.9154342=0.0845658$

If the number of students in the class = 60 .

Then , the number of students will be unable to complete the exam in the allotted time = $0.0845658\times60=5.073948\approx5$
