Answer #1

Answer is:

Calculations:

Using the excel the distribution is:

X P(X=x)
0 0.0167962
1 0.0895795
2 0.2090189
3 0.2786918
4 0.2322432
5 0.1238630
6 0.0412877
7 0.0078643
8 0.0006554

Use excel formula =BINOM.DIST(3,8,0.4,TRUE)=0.5940864

Compute​ P(X) using the binomial probability formula. Then determine whether the normal distribution can be used to estimate this probability. If​ so, approximate​ P(X) using the normal distribution and compare the result with the exact probability. n=50​, p=0.50​, and x=17 For n=50​, p=0.5​, and X=17​, use the binomial probability formula to find​ P(X). Q: By how much do the exact and approximated probabilities​ differ? A. ____​(Round to four decimal places as​ needed.) B. The normal distribution cannot be used.
