Assignments will be typed and uploaded in a word document to blackboard. The average age for licensed drivers in a county is 42.6, with a standard deviation of 12, and the distribution is approximately normal.

On the basis of her newly developed technique, a student believes she can reduce the amount of time schizophrenics spend in an institution. As director of training at a nearby institution, you agree to let her try her method on 20 schizophrenics, randomly sampled from your institution. The mean duration that schizophrenics stay at your institution is 85 weeks, with a standard deviation of 15 weeks. The scores are normally distributed. The results of the experiment show that patients treated...
For each problem students will write out all steps of hypothesis testing including populations, hypotheses, cutoff scores, and all relevant calculations. Assignments will be typed and uploaded in a word document to blackboard. A psychologist has developed a standardized test for measuring the vocabulary skills of 4-year- old children. The scores on the test form a normal distribution with μ-60 and σ-10. A researcher would like to use this test to investigate the idea that children who grow up with...
