SAT scores have a mean of 1026 and a standard deviation of 209. ACT scores have a mean of 20.8 and a standard deviation of 4.8. A student takes both tests while a junior and scores 1130 on the SAT and 25 on the ACT. Compare the scores. The two scores are statistically the same. The two scores are statistically the same. You cannot determine which score is better from the given information. You cannot determine which score is better from the given information. A score of 25 on the ACT test was better. A score of 25 on the ACT test was better. A score of 1130 on the SAT test was better.
Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the range, variance, and standard deviation for the sample data. Given that these are the top 10 salaries, do we know anything about the variation of salaries of TV personalities in general? 42 41 39 31 23 21 18 17 16.8 16.1 O The range of the sample data is $ million. (Type an integer or a decimal.) The variance of the sample data is (Round to two decimal places as needed.) The standard deviation of the sample data is $ (Round to two decimal places as needed.) million Is the standard deviation of the sample a good estimate of the variation of salaries of TV personalities in general? O A. No, because there is an outlier in the sample data. B. Yes, because the sample is random. C. No, because the sample is not representative of the whole population. O D. Yes, because the standard deviation is an unbiased estimator. Next
A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1457 and the standard deviation was 315. The test scores of four students selected at random are 1900, 1200, 2180, and 1350. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The is the z-score for 1900?
The earned run average of the two players is 3.7 each but the mean absolute deviation (MAD) for Ashley is 1.7 and for Kimberly is 0.6. The coach wants the best overall play; which player would the coach prefer to choose?
Use z scores to compare the given values. The tallest living man at one time had a height of 233 cm. The shortest living man at that time had a height of 89.9 cm. Heights of men at that time had a mean of 176.34 cm and a standard deviation of 5.47 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= height that was more extreme. (Round to two decimal places.) and the z score for the shortest man is z = the man had the
IQ scores are measured with a test designed so that the mean is 114 and the standard deviation is 14. Consider the group of IQ scores that are unusual. What are the z scores that separate the unusual IQ scores from those that are usual? What are the IQ scores that separate the unusual IQ scores from those that are usual? (Consider a value to be unusual if its z score is less than - 2 or greater than 2.) What are the z scores that separate the unusual IQ scores from those that are usual? The lower z score boundary is (Simplify your answer.) The higher z score boundary is (Simplify your answer.) What are the IQ scores that separate the unusual IQ scores from those that are usual? The lower bound IQ score is (Simplify your answer.) The higher bound IQ score is (Simplify your answer.)
THE SCORES ON THE SAT MATH HAD A MEAN OF 431 AND A STANDARD DEVIATION OF 117. What percent of students scored between a 314 and 548? THE SCORES ON THE SAT MATH HAD A MEAN OF 431 AND A STANDARD DEVIATION OF 117? How many students scored between a 314 and 548 if 800 students were taking the test? Find the z-score of a car getting 22.4 mpg if the mean mpg is 23.5 with a standard deviation of 1.5 mpg. Round to nearest hundredths if needed.
Assume that the SAT test scores are normally distributed with a mean score of 1200 and a standard deviation of 150. ACT test scores are normally distributed with a mean score of 22 and a standard deviation of 3 Mike scored 1250 on the SAT. What proportion of all test takers did Mike score higher than? If Mike scored a 1250 on the SAT and Jes scored a 26 on the ACT, then who's score is relatively better?
Mario scored 82 on his history final. The class mean was 78 with a standard deviation of 3 points. He scored 72 on his biology final with a mean score of 65 and a standard deviation of 5 points. Which grade was better compared with the class mean referencing a normal distribution? a. The biology test is better. The z-scores for the biology exam and the history exam respectively are 1.4 and 1.33. b. The biology test is better. The z-scores for the biology exam and the history exam respectively are 1.33 and 1.4. c. The history test is better. The z-scores for the biology exam and the history exam respectively are 1.33and 1.4. d. The history test is better. The z-scores for the biology exam and the history exam respectively are 1.4 and 1.33.
Use z scores to compare the given values. The tallest living man at one time had a height of 225 cm. The shortest living man at that time had a height of 104.3 cm. Heights of men at that time had a mean of 173.55 cm and a standard deviation of 5.15 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= and the z score for the shortest man is z= the V man had the height that was more extreme. (Round to two decimal places.)
Use z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallest
