Information In the 19805, it was generally believed that congenital abnormalities affect about 5% of a nations children.Some people believe that the increase in the number of chemicals in the environment in recent years hasled to an increase in the incidence of abnormalities. A recent study examined 376 children and found that 27 of them showed signs of an abnormality. Using the worksheet provided (Right click the blue words, ‘Open Link In New Tab’) in the course materials,set the hypothesis, check the conditions for a one-proportion z-test, and calculate the P-value. Perform this test on your own and answer questions 10, 11, and 12 based on your results.Question 10 (1 point) ElThe 10% Condition is satis?ed. 0 True 0 False SaveQuestion 11 (1 point) After checking the conditions, the next step is to perform a one-proportion z-test and obtain the P-value. Select the answer with the z-score and P-value closest to the values youve calculated. The z-score is: -1.957 The P-value is: 0.052 The z-score is: 1.957 The P-value is: 0.025 The z-score is: -1.00 The P-value is: 0.05 The z-score is: 2.96 The P-value is: 0.025Question 12 (1 point) ’31] Select the most correct conclusion statement from the four options below. m Based on the P-value, we can conclude that there is weak evidence with which to fail to reject the nullhypothesis. This supports the alternative hypothesis of a rise in incidences of abnormalities. m Based on the P-value, we can conclude that there is strong evidence with which to fail to reject the null” hypothesis. This does not support the alternative hypothesis of a rise in incidences of abnormalities. ? Based on the P-value, we can conclude that there is weak evidence with which to reject the nullhypothesis. This supports the alternative hypothesis of a rise in incidences of abnormalities. In. Based on the P-value, we can conclude that there is strong evidence with which to reject the null” hypothesis. This supports the alternative hypothesis of a rise in incidences of abnormalities.Question 13 (1 point) {all A study of the effects of climate change on trees in the remaining Carolinian Forest in Ontario shows that 25 of100 trees sampled exhibit some sort of change in the reproductive cycle patterns. This rate seemed to behigher than the 15% quoted in a recent research article on the average proportion of pine trees responding to climate change in a nearby location in Southern Ontario. (Note: The samples were taken from trees closest tothe road). Does the sample suggest that the susceptibility of trees in Carolinian Forests differs from the susceptibility ofpine trees in Southern Ontario? Select the appropriate hypotheses, perform a hypothesis test, and select all of the following statements thatare true. [1 HA : The proportion of trees affected by climate change in Carolinian Forest has increased above 15%,_ similar to the increase of the proportion of affected pines in Southern Ontario. 0 The sample is large enough to satisfy the Success/Failure Condition. Cl The Randomization Condition is not satisfied. Cl H0 : The proportion of trees affected by climate change in Carolinian Forest less than 15%. ? Since the P-value is low, there is strong evidence that the trees in Carolinian forest are more susceptible, to climate change than trees of pine plantations in Southern Ontario.
