Hypotheses, the sample statistic, and the standard error are given. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Assume the sample size is large enough to use the standard normal distribution.
Test H0 : p=0.35 vs Ha : p>0.35 when the sample has p^=0.41 and the standard error is SE=0.02. Round your answers to three decimal places.
a) test statistic =
b) p-value=
Homework Answers
a) The test statistic is given by 
b) Since the alternate hypothesis is 
, the p-value is
just the probability that a standard normal random variable takes a
value >3. This probability is 0.00135.
