21.  A random sample of n bike helmets manufactured by a certain company is selected. Let X = the num- ber among the n that are awed, and let p = P( awed). Assume that only X is observed, rather than the sequence of S s and F s.
a.  Derive the maximum likelihood estimator of p. If
n = 20 and x = 3, what is the estimate?
b.  Is the estimator of part (a) unbiased?
c.   If n = 20 and x = 3, what is the mle of the prob- ability (1 - p)5 that none of the next ve helmets examined is awed?
