Researchers want to determine if there is a connection between choice of musical instruments and gender. They want to see if the proportion of men (m) who play the flute is different from the proportion of women (f) who play the flute. They find that the p-value is 0.11. What can be said about the 99% confidence interval for the population mean difference?

A study exаmined the hypоthesis thаt оwning а pet has a pоsitive effect on mental health. A "Happiness Inventory" was used, with possible scores ranging from 1 to 15 (15 meaning most happiness). The findings were as follows: df = 10, t = 2.98, mean happiness for the pet owners = 11.14, mean happiness for those who do not own pets = 6.40. The critical boundaries are +/- 2.228 for an alpha = .05, two-tailed test. For 3.5 points of extra credit: 1) Please write-up this result according to APA style recommendations.
