Solved As Per Chegg Policy Answer All Parts Of Chegg Question: in 2012, the mean score on the act test was 21.1 and the standard deviation was 5.2. the mean score on the sat mathematics test was 514 and the standard deviation was 117. the distributions of both scores were approximately bell shaped alexandra scored a 24 on the act. cheryl scored a 600. which score is higher relative to its population?. If the average act score was 21 and the standard deviation was 5, we would expect a score of 24 to yield a positive z score, signaling better relative performance.
Solved In 2012 The Mean Score On The Act Test Was 21 1 And Chegg In 2012 the mean score on the act test was 21.1 and the standard deviation was 5.2. the mean score on the sat math test was 514 and the standard deviation was 117. the distributions of both scores were approx. bell shaped. Z score: in this question, we will use the z score formula to calculate the score values. the z score is a standard normal variate and follows normal distribution with mean 0 and. It is calculated using the following formula: σ is the standard deviation of the population. the student who did better is the one with the higher z score, because a higher z score indicates that the score is further above the mean. after calculating the z scores, compare them. Find step by step precalculus solutions and the answer to the textbook question in 2012, the national mean act math score was 21.0, with an approximate standard deviation of 6. act scores in the general population approximate a normal distribution. mean act scores are published state by state.
Solved In A Particular Year The Mean Score On The Act Test Chegg It is calculated using the following formula: σ is the standard deviation of the population. the student who did better is the one with the higher z score, because a higher z score indicates that the score is further above the mean. after calculating the z scores, compare them. Find step by step precalculus solutions and the answer to the textbook question in 2012, the national mean act math score was 21.0, with an approximate standard deviation of 6. act scores in the general population approximate a normal distribution. mean act scores are published state by state. Step 1: identify the given in the problem stated. the mean score is 21.1 and the standard deviation of 5.2. the unknowns are the z scores that corresponds to 26 and the score that corresponds to the z score of 0.75. step 2: formulate the equation to be solved. The z score for an act score of 27, using a mean of 21.1 and a standard deviation of 5.2, is approximately 1.13. this result indicates that the score of 27 is 1.13 standard deviations higher than the mean act score. In 2012, the mean score on the act test was 21.1 and the standard deviation was 5.2. the mean score on the sat mathematics test was 514 and the standard deviation was 117. the distributions of both scores were approximately bell shaped. (a) find the z score for an act score of 27. (b) find the z score for an sat math score of 650. (c) which. This means that a score of 26 is about 0.94 standard deviations above the mean score of 21.1 on the act test. a positive z score indicates that the score is above average, while the magnitude shows how far it is from the mean.
Solved Suppose The Act Score Was Centered On The Mean Act Chegg Step 1: identify the given in the problem stated. the mean score is 21.1 and the standard deviation of 5.2. the unknowns are the z scores that corresponds to 26 and the score that corresponds to the z score of 0.75. step 2: formulate the equation to be solved. The z score for an act score of 27, using a mean of 21.1 and a standard deviation of 5.2, is approximately 1.13. this result indicates that the score of 27 is 1.13 standard deviations higher than the mean act score. In 2012, the mean score on the act test was 21.1 and the standard deviation was 5.2. the mean score on the sat mathematics test was 514 and the standard deviation was 117. the distributions of both scores were approximately bell shaped. (a) find the z score for an act score of 27. (b) find the z score for an sat math score of 650. (c) which. This means that a score of 26 is about 0.94 standard deviations above the mean score of 21.1 on the act test. a positive z score indicates that the score is above average, while the magnitude shows how far it is from the mean.
Solved Determine The Mean Of The Following Test Scores Chegg In 2012, the mean score on the act test was 21.1 and the standard deviation was 5.2. the mean score on the sat mathematics test was 514 and the standard deviation was 117. the distributions of both scores were approximately bell shaped. (a) find the z score for an act score of 27. (b) find the z score for an sat math score of 650. (c) which. This means that a score of 26 is about 0.94 standard deviations above the mean score of 21.1 on the act test. a positive z score indicates that the score is above average, while the magnitude shows how far it is from the mean.
