- The critical chi-square value for 15 degrees of freedom when alpha=.05 and the test is right-tailed is 19.675. True FalseYou are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.24. Thus you are performing a left-tailed test. Your sample data produce the test statistic z=−2.287z=-2.287. Find the p-value accurate to 4 decimal places.p-value =A researcher was doing a study for a new Coronavirus Drug and conducted a hypothesis test like this one: H0: μμ = 15 Ha: μμ ≠≠ 15 a. What type of test is this? two-tailed left-tailed right-tailed b. She obtained a test statistic of -1.21, with a p-value of 0.245. So she concluded that her true mean must be equal to 15. Is this interpretation correct? Yes No Why or why not? (Will be graded manually!)v
