consider a study that compares the Atkins diet to a conventional diet. A study at the University of Pennsylvania selected a sample of 63 subjects from the local population of obese adults. Researchers randomly assigned 33 to the Atkins diet and 30 subjects to a conventional diet. Test whether there is a significant difference in the mean weight loss (measured in pounds) across the two different diet programs. Using software: Generate summary statistics (central tendency and variability measures) for the...

It appears that sons of fathers who display low self-esteem tend to develop low self-esteem as well. Kuya conducted a study to test this hypothesis, since he is pretty sure that there must be a difference between the two groups, with sons having higher self-esteem than their fathers. He measured the self-esteem of the fathers and their sons using the Fearful Insecure Neurotic Emotional (FINE) test. The higher the score, the lower is the self-esteem. Is there a significant difference?...
