Nota, Ferrari, Soresi, and Wehmeyer (2007) measured the relationship between IQ and the four measures of self-determination in a sample of n = 141 participants. They reported a negative correlation between IQ and self-determination in daily activities, r = -0.42, p < .01, and a negative correlation between IQ and self-determination in expressing emotions and options, r = -0.16, p > .05. a. Which correlation is significant? b. Which is the stronger correlation?
A research study investigates the occurrence of extra heartbeats between untrained and trained older patients at risk for heart attack.

Historically, Olympic officials have reported testosterone levels in general should be u = 538 ng/dL, with o = 189, with x being normally distributed. Summer Olympic sprinters (n = 8) from the U.S. were tested for testosterone levels the morning after the opening ceremonies. Their sample mean was ng/dL. Do these data indicate that the sprinters had an overall average testosterone level greater than 538? Use a = .05. State a, H,, H1, p-value, rejection, or non-rejection, and be certain to interpret your results.
