Nonparametric: A small study is conducted to compare birth weight in babies born to mothers who do not smoke to those that smoke more than 2
pack/day. Is there a significant difference between birth weights due to maternal smoking status? Use the Mann-Whitney U test with a 5% level of
significance. What is U1 (non-smokers)?

What experiment could Jeffrey design to test his hypothesis?arrow_forwardTest the hypothesis a. There is no significant difference between the perceived level of riskiness of thrill behavior in males and in females (a=0.05) b. There is no significant difference between the perceived level of riskiness of rebellious behavior in males and in females (a=0.10) c. There is no significant difference between the level of riskiness of thrill-seeking items and rebellious items as perceived by the males (a=0.05)arrow_forwardMark performed a two-sample z-test for proportions to test the hypothesis that there was no difference in the proportion who support increasing student fees between male and female students at a particular university. Mark obtained a z-statistic of 0. Based on this information, which of the following is always true. The sample proportions for male and females will be the same as the hypothesized proportions for male and female students at this university. The sample proportions for both male and female students at this university will be 0. All male and female students in the sample will feel the same way about supporting the increase in student fees. The sample proportions will be the same for both male and female students at this university. Test whether p1>p2 The sample data are x1=116,n1=258,x2=135,n2=311.

A health researcher is interested in comparing 3 methods of weight loss: low calorie diet, low fat diet and high exercise regimen. He selected 15 moderately overweight subjects and randomly assigned 5 to each weight-loss program. The following weight reductions (in lbs) were observed after a one-month period. Test the hypothesis that the extent of weight reduction does not differ by type of weight-loss program.
