The alternative hypothesis is μ > ______ What is the critical t? _________ Calculate the t value and round to 2 decimals: _______ With alpha = .05. can she reject the null (type yes or no)? _______
A gender psychologist is interested in studying whether children, when left on their own, actually show more interest in toys associated with their assigned gender. The psychotherapist allows the participants (n = 16) to move freely back and forth for 40 minutes between two rooms, one of which contains toys traditionally associated with girls and another which contains toys traditionally associated with boys. She collects the data and finds that on average the children spend 23 minutes in the room (M = 23) with the toys associated with their assigned gender, with a standard deviation of s = 9. She conducts a one-tailed test and sets the alpha at .05.
