- The test statistic for Ho: p = 0.75 versus HA: p > 0.75 is z = -3.05. What is the p-value for this test? Round to four decimal places. p-valueIn testing Ho: p = .5 against H1:p > .5, 400 voters were surveyed and 216 reported they were in favor of the proposal to widen I-485. Fill in the blank for each of the following questions. Find the p-value for this test Enter you answer accurate to four (4) decimal places.Calculate the z-score of the given x value, x = 52, where u = 46.6 and σ = 41.9. Round your answer to two decimal pla
- (b) Calculate the P-value. P-value = (Round to three decimal places as needed.)Big babies: The National Health Statistics Reports described a study in which a sample of 354 one-year-old baby boys were weighed. Their mean weight was 25.8 pounds with standard deviation 5.3 pounds. A pediatrician claims that the mean weight of one-year-old boys is greater than 25 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the a=0.05 level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of 5Determine the z-score given the following: (Express your answers in 2 decimal places) 1. P(z
- Give the value of the test statistic t for this situation: H0: ?d = 0, Ha: ?d ≠ 0, d = −4, sd = 15, n = 50. (Round the test statistic to two decimal places.) t=_____= .7 and =.6. Test Ho: (P, - P2) =0 against H,:(P, – P2)>0 using a = .05Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye. Time to Complete the Course Right 46 48 42 50 46 43 50 41 Left 45 46 42 50 46 39 50 37 Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of significance?
