B. .9146

c. Part B

D..0548

Step-by-step explanation:

This is the same for parts A,B, and D just plug in the different numbers.

Z=(x-μ)/σ

B. 2.15/ $\sqrt{50}\\$

=.2899

$\frac{18.30-18.80}{.2899}$

=1.724732667

Look up in your z score table +/- 1.72

You should get +.9573

-.0427

So take .9573-.0427= .9146 <-- thats the answer!!

Good Luck Pal!!
