Researchers developed a "cat IQ test" and find that the population of cats in the United States has a mean score of µ = 25 on this test with a standard deviation of σ = 3. You decide to test a sample of n = 45 cats to do some research about whether some breeds are smarter. What is the cat IQ range for the middle 50% of all cats? (Hint: find the Z-score with a probability closest to 0.25, because you want 25% above the mean and 25% below the mean to get the 'middle 50%', and then use that to find the IQ that matches.)
