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)
