How is the value of SY, related to the size of r? Why?
Answer to relevant Questions(a) What does probability convey about an event’s occurence in a sample? (b) What is the probability of a random event based on? The mean of a population of raw scores is 33 (σx = 12). Use the criterion of .05 and the upper tail of the sampling distribution to test whether a sample with X = 36.8 (N = 30) represents this population. (a) What is the ...We reject that a sample, with X = 95, is merely poorly representing the population where µ = 100. (a) What is our best estimate of the population µ that the sample is representing? (b) Why can we claim this value of µ? ...What is the difference between using both tails versus one tail of the sampling distribution in terms of (a) The size of the region of rejection? (b) The critical value? Foofy claims that a one-tailed test is cheating because we use a smaller zcrit, and therefore it is easier to reject H0 than with a two-tailed test. If the independent variable doesn’t work, she claims, we are more likely ...
