The New York Times (2/5/90) reported three-point shooting performance for the top 10 three-point shoot- ers in the NBA.

Note: FGA = field goals attempted and FGM = field goals made.
For a given player, the outcome of a particular shot can be modeled as a Bernoulli (zero-one) variable:
if Y, is the outcome of shot i, then Y, = 1 if the shot is made, and Y; = 0 if the shot is missed. Let 0
denote the probability of making any particular three-point shot attempt. The natural estimator of 0 is
Y = FGM|FGA.
(i) Estimate 0 for Mark Price.
(ii) Find the standard deviation of the estimator Y in terms of 0 and the number of shot attempts, n.
(iii) The asymptotic distribution of (Y – 0)/se(Y) is standard normal, where se(T) = VT(1 – Y)/n.
Use this fact to test H,: 0 = .5 against H,: 0 < .5 for Mark Price. Use a 1% significance level.
