Test: POST UNIT 4 Test CH 6 & 7 Question 7 of 13 This test: 13 point(s) possible This question: 1 point(s) possible Submit test One graph in the figure represents a normal distribution with mean u = 14 and standard deviation o = 3. The other graph represents a normal distribution with mean p = 10 and standard deviation o = 3. Determine which graph is which and explain how you know. 10 14 Choose the correct answer below. O A. Graph A has a mean of u = 14 and graph B has a mean of = 10 because a larger mean shifts the graph to the left. O B. Graph A has a mean of u = 14 and graph B has a mean of u = 10 because a larger mean shifts the graph to the right. O C. Graph A has a mean of u = 10 and graph B has a mean of u = 14 because a larger mean shifts the graph to the right. O D. Graph A has a mean of u = 10 and graph B has a mean of u = 14 because a larger mean shifts the graph to the left.

E Test: POST UNIT 4 Test CH 6 & 7 Question 9 of 13 This test: 13 point(s) possible This question: 1 point(s) possible Submit test Suppose the lengths of human pregnancies are normally distributed with u = 266 days and G = 16 days. Complete parts (a) and (b) below. (@) The figure to the right represents the normal curve with u = 266 days and o = 16 days. The area to the left of X= 250 is 0.1587. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The proportion of human pregnancies that last less than days is. O B. The proportion of human pregnancies that last more than days is X 250 268 Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The probability that a randomly selected human pregnancy lasts less than days is O B. The probability that a randomly selected human pregnancy lasts more than days is (b) The figure to the right represents the normal curve with u = 266 days and o = 16 days. The area between x = 285 and x = 300 is 0.1007. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Use ascending order.) O A. The proportion of human pregnancies that last less than or more than days is O B. The proportion of human pregnancies that last between and days is X 266 285 300 Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Use ascending order.) O A. The probability that a randomly selected human pregnancy lasts between and days is O B. The probability that a randomly selected human pregnancy lasts less than or more than days is
