Z score will be
= (95-100)/15
= -1/3
= -0.33
So, Option B is Correct
Option B is Correct
IV. Assume that IQ scores are normally distributed, with a mean of 100 and standard deviation of 15. What is the probability that a randomly selected person has an IQ score a greater than 120? b. less than 902 c. between 90 and 120? d. between 105 and 120?
1. The typical IQ test is designed with a mean of 100 and standard deviation of 15. Find Z score corresponding to IQ score of 128 (4 points) Z=

The IQ scores of adults are normally distributed with a mean 100 and a standard deviation of 15. If a group of 64 adults is randomly selected, what is the probability that their mean IQ will be at least 95? A. 0.6293 B. 0.3707 C. 0.9962 D. 0.0038
In a large population of prisoners, the mean IQ is 95 with a standard deviation of 15. 250 adults from this population are randomly selected for a survey of attitudes toward crime. a. What is the mean of this sampling distribution (all samples of n = 250)? b. What is the standard deviation of the sampling distribution? c. What is the shape of sampling distribution? d. If an individual prisoner has an IQ of 90, is she a likely or...
IQ-scores are standard-score transformed scores having a mean of 100 and a standard deviation of 15; SAT scores are standard-score transformed scores having a mean of 500 and a standard deviation of 100. In what follows, X refers to a raw score from a distribution with a mean of X and a standard deviation of S, and SAT and IQ refer to the corresponding transform of that score. Solve for the missing value in each of the following: (a) X=-2.5;Xmean=...
Intelligence quotient (IQ) scores are often reported to be normally distributed with a mean of 100 and a standard deviation of 15. (a) If a random sample of 50 people is taken, what is the probability that their mean IQ score will be less than 95? (b) If a random sample of 50 people is taken, what is the probability that their mean IQ score will be more than 95? (c) If a random sample of 50 people is taken,...
We are interested in examining the IQ scores of college students versus the average population IQ. We take a sample of 25 college students and have them take the WAIS. Our sample of college students had an average WAIS of 110, and the known population mean for the WAIS is 100 with σ= 15. a. What type of statistical test should we conduct (z score, one sample t test, independent measures t test, repeated measures t test)? How do you...
IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. A sample of 10 children in a gifted learner program are found to have a mean IQ of 106. Use a z-test to determine if this is significantly different from the normal population mean. What are your specific null and alternative hypothesis? Z=+ - 1.96 standard deviation m= 4.743 Z= 1.26 Will you reject or retain the null hypothesis? We will retain the null...
On IQ distribution (normal) , with a mean of 100 and a standard deviation of 15 , find the actual IQs (raw scores) for individuals with the following z scores. 1) .60 2) 2.60 3) -1.80 4) -.20 5) 2.80
IQ scores are normally distributed with a population mean of 100 and SD 15. If you select a sample of 25 individuals how high would the sample mean have to be to say that probability of getting a sample mean that high or higher is 0.05? Round your answer to whole number.
