A researcher wants to study sports-watching behavior of young men. In a random sample of 18 young adult men 20-30 years old, each person was asked how many minutes of sports he watched on TV daily. The researcher wishes to test whether the mean amount of television watched daily by young men is greater than 50 minutes.
What would be a Type I error, in the context of this problem?
a. The researcher concludes that the mean amount of television watched by young men is greater than 50, when the mean is really greater than 50.
b. The researcher concludes that the mean amount of television watched by young men is greater than 50, when the mean is really less than or equal to 50.
c. The researcher concludes that the true mean amount of television watched by young men is equal to 50, when the mean is really less than 50.
d. The researcher fails to conclude that the mean amount of television watched by young men is greater than 50, when the mean is really greater than 50.
e. The researcher concludes that the mean amount of television watched by young men is less than or equal to 50, when the mean is really less than or equal to 50.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
