A psychiatrist hires you to study whether her clients self-disclosed more while sitting in an easy chair or lying down on a couch. All clients had previously agreed to allow the sessions to be videotaped for research purposes. You randomly assigned 10 clients to each condition. The third session for each client was videotaped and an independent observer counted the clients' disclosures. You reported that "clients made more disclosures when sitting in easy chairs (M = 18.20) than when lying down on a couch (M = 14.31), t(18) = 2.84, p < .05, two-tailed." Explain these results to a person who understands the t test for a single sample but knows nothing about the t test for independent means.
At the .05 level of significance, can we conclude the Middletown students stayed in their districts less time than the Brockton students? Use the five-step hypothesis testing procedure.

If the decision in the hypothesis test of population correlation is to reject the null hypothesis, what can we conclude about the population correlation.
Which of the following is true about the expected value of perfect information. It is the amount you would pay for any sample study.
What is the probability that the sum of their scores exceeds 1200 and probability that the average of the scores of all 400 student
The mean of a normal probability distribution is 60; the standard deviation is 5.
Determine the probability, P(Z
What maximum variance of the raw score population could you have and still be able to reject the null hypothesis of μ = 20 (α = .05), if the sample size is 100 and the sample mean is 22?
A random sample of 36 days yielded the average daily output of 890.2 tons, with standard deviation of 19.8 tons. Use this information to make a 95% confidence interval for mean.
Fifty raffle tickets are numbered 1 throughout 50, and one of them is drawn at random. What is the probability that the number is a multiple of 5 or 8? Consider the following "solution": Since 10 tickets bear numbers that are multiples of 5 and 6 ..
