Suppose you want to estimate the proportion of polydactyl cats (cats with extra toes). you sample 419 randomly selected cats, and find 56 polydactyls. you have no prior assumption to test- you only want to estimate the proportion. should you carry out a hypothesis test using the sample proportion 56/419 as your null hypothesis? select the best answer. yes. your null should be: the proportion of cats who are polydactyl is 56419, or 13.4%. 0 a. no. you should have a null hypothesis that the proportion of cats who are polydactyl is 0, since it's a genetic defect. o b. ° c. no. 419 isn't 10 times larger than 56. o d. no. there's no way to get a truly random sample. no. when all you wantto do isestimate a population parameter, you should construct a confidence interval. e. o f. i'm not sure.
