The accepted average IQ score of the United States is 98, with a standard deviation of 15. The principal at Waterford High School claims the students in his school are above average intelligence. The distribution of IQ scores is not Normal. What does this tell us about the necessary sample size?

The average IQ score is 98.5. The variable is normally distributed, and the population standard deviation is 18. A school superintendent claims that the students in her school have an IQ greater than the average. She selects a random sample of 35 students and finds that the mean of the tests scores is 110.2. Test the claim at ̑́ = 0.05. a) State the hypothesis: b) Find the critical value(s). (Round the nearest hundredths) c) Compute the test statistic. (Round the nearest hundredths) d) Make a decision. e) Summarize your conclusion in a COMPLETE SENTENCE.

An IQ test is designed so that the mean is 100 and the standard deviation is 15 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 90% confidence that the sample mean is within 7 IQ points of the true mean. Assume that σ = 15 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is . (Round up to the nearest integer.) Would it be reasonable to sample this number of students? Yes. This number of IQ test scores is a fairly small number. Yes. This number of IQ test scores is a fairly large number. No. This number of IQ test scores is a fairly small number. No. This number of IQ test scores is a fairly large number.
