Test the claim that the percentage of workers in a city that are employed full time is more than 81%. A random sample of 74 workers finds that 83.78% work full time. Use a = 0.05. 1. The sample size restriction for this test is: O Need at least 5 successes and 5 failures O Need n > 30 O None needed since population is normally distributed The hypotheses are: О Но:р 3 0.81%; На:р + 0.81 О Но:р < 0.81;B На:р > 0.81 O Ho:p 0.81; Ha:p < 0.81 O Ho:u <81; Ha:u > 81 O Ho:u = 81; Ha:u+ 81 Ο Ho: μ > 81; Ha μ < 81 2. This is a O leftO rightO two tailed test and the distribution used is OT since o not known OZ since testing a proportion OZ since a known The Degrees of Freedom are O74 ON/A since this is a Z-test
