Problem 6.13 For a test of Ho : n = 0.50, the sample proportion is 0.35 based on a sample size of 100. (a) Show that the test statistic is z = -3.0 (b) Find and interpret the P-value for H: <0.50 (c) For a significance level of a = 0.05, what decision do you make? (d) If the decision in (c) was an error, what type of error was it? What could you do to reduce the chance of that type of error?
