Q16

Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and these scores are normally distributed with a mean of 100 and a standard deviation of 15. 0.1285 The indicated IQ score is D. (Round to the nearest whole number as needed.) If we collect a large sample of blood platelet counts and if our sample includes a single outlier, how will that outlier appear in a histogram? Choose the correct answer below. A. The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1. B. The outlier will appear as a tall bar near one side of the distribution. Since a histogram shows frequencies, not individual data values, the outlier will not appear. Instead, the outlier increases the frequency for its class by 1. {:ji- D. The outlier will appear as the tallest bar near the center of the distribution. Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. 106 124 (E The area of the shaded region is D. (Round to four decimal places as needed.) Consider a score of 60 on a test with a mean of 69 and a standard deviation of 14, and consider a score of 405 on a test with a mean of 488 and a standard deviation of 143. Which score is better? E) {I} A. The score of 60 (:22- B. Can not be determined from the information given {II- C. Both scores have the same relative position {:22- D. The score of 405 (Recorded Speeds). Suppose the speed of 22 cars are recorded on a local highway with the minimum = 88 km/h and maximum = 122 km/hr. Suppose the last speed observed was recorded incorrectly, and should have been 132 km/h instead of 122 km/h. If the statistics are recalculated, which of the following four (4) statements are false? (i) The old mean will be smaller than the new mean (ii) The new median will be larger than the old median (iii) The new standard deviation will be larger than the old standard deviation (iv) The new range will be larger than the old range . . . O A. (i) and (iii) only O B. All four (4) statements are true O c. (ii) and (iv) only O D. (i), (ii) and (iii) only O E. (i) only OF. (ii) only O G. None of the four (4) statements are false OH.
