The standard IQ test is designed so that the mean is 100 and the standard deviation is 15 for the population of all adults. We wish to find the sample size necessary to estimate the mean IQ score of statistics students. Suppose we want to be 96% confident that our sample mean is within 1 IQ points of the true mean. The mean for this population is clearly greater than 100 . The standard deviation for this population is probably...

For randomly selected adults, IQ scores are normally distributed with a standard deviation of 15. For a simple random sample of 25 randomly selected college students, their IQ scores have a standard deviation of 18. Use a 5% level of significance; test the claim that the IQ scores of college students are less consistent (higher standard deviation) compare to the IQ scores of the general population.

The IQ scores for adults in the entire population have an approximate normal distribution with mean 100 and standard deviation 15. A study done on 200 college students (ages 20 to 25) found college student age 20 to 25 have an average IQ of 105. Do college students aged 20 to 25 years old have a higher mean IQ than the rest of the population? Even if this does have statistical significance (meaning it is actually true), do you think...
