You're fired! Suppose that in a random sample of 266 employed Americans, there are 66 individuals who say that they would fire their boss if they could. Round all calculated values in this problem to 4 decimal places. 1. The value 66/266 = 0.2481 is a Statistic We want to use the information from the sample to conduct a hypothesis test to determine if fewer than 29% of employed Americans would fire their boss if they could. 2. Choose the null and alternative hypotheses for this test. Use appropriate notation. OA. Ho : p = 0.29, HA : p > 0.29 ов. Но : р3D 0.29, НА :р<0.2481 OC. Ho : p = 0.29, HA : p # 0.29 OD. Ho : p = 0.29, HA: p < 0.29 3. If you assume that the observations in the sample are independent, what is the smallest value the sample size could be to meet the conditions for this hypothesis test? OA. 20 OB. 35 OC. 10 OD. 41 OE. 66 OF. None of the above 4. Calculate the test statistic. z = 5. Calculate the p value. p =
