The survey rate for a college is 42 percent. Assuming the binomial to the normal distribution. Of the next rates 10 what is the probability the colleges will have. (Round to 4-decimals)

A. Find the mean

B. Calculate the standard deviation

C. Exactly four? P(X=4)

d. Would it be unusual for them to rate none or more than 7 surveys?

E. Between four and six surveys.

P(4< x <6) = P(x=4) +P(x=5)+P(x=6)
