You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.2. You use a significance level of a - 0.05 Ho p 0.2 H1: p 0.2 You obtain a sample of size n = 336 1in which there are 61 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) P-value = The p-value is.. less than (or equal to) o greater than a This test statistic leads to a decision to. reject the nul1 a
