Question
Last week, Bob had a score ofX 45 on a mathematics exam and a score ofx 61 on an English exam. Ifthe math exam scores had amean of u 40 with a 5, and the English exam scores had amean of u 51 with a 10, for which exam should Bob expect the better grade English r The two exam scores are in equivalent locations soBob shouldexpect the same srade in both classes. cannot answer without additional information mathematics A population with u 85 and a 12 is transformed into 2-scores. After the transformation, the population ofz-scores will have standard deviation of cannot be determined from the information given a 12 a 1.00 A very bright student is described as having an IQ that is three standard deviations above the mean. If this student's IQ is reported as a2-score, the z-score would be H+30 cannot be determined from the information given Az-score of z 2.00 indicates a position in a distribution below the mean by 2 points below the mean by a distance equal to 2 standard deviations above the mean by a distance equal to 2 standard deviations above the mean by 2 points Under what circumstances would a score that is 15 points above the mean be considered an extreme Score? when the population standard deviation ismuch larger than 15 when the population mean is much larger than 15 when the population standard deviation is much smaller than 15 when the population mean is much smaler than 15 For a population with a 4, an individual with a deviation score of +2 would have a z-score of +2.00 cannot be determined without knowing the population mean +8.00 +0.50 Suppose you earned a score of 45 on an exam. Which set of parameters would give you the highest grade? H 350 and a 32 H 55 and 10 10 5s and 2 A population has u 50 and a these scores are tra nsformed into z-scores, the population of z- score will have a mean of and a standard deviation of 0 and 10 50 and 1 50 and 10 0 and 1. The mean for any distribution corresponds to a zscore ofExplanation / Answer
2)
The correct answer is sigma = 1
Population mean is 85
Stdev is 12
After the transformation , the standard deviation of the standardized normal dsitribution is 1
The standardized normal dist has params of Mu,Sigma = (0,1)
