Situation B: An independently selected sample of five men also participated in the same study. The table below shows results for the number of pounds lost by the five men and five women in the study. The researcher will use the .01 significance level to test whether (on average) the program produces different weight-loss results for men and women. You may assume that the population variances are equal (although the sample variances are not).

***Weight-loss is in pounds***

Men (sample 1): sample size- 5, sample mean- 19.2, standard dev.- 4.970

Women (sample 2): sample size- 5, sample mean- 12.6, standard dev.- 4.336

1) Choose the appropriate formula for the test statistic and find its value.

A sample of 15 patients suffering from asthma participated in an experiment to study the effect of a new treatment on pulmonary function. Among the various measurements recorded were those are forced expiratory volume (liters) in 1 second (FEV1) before and after application of the treatment. Suppose the researcher would like to test if the treatment is effective in increasing the FEV1. Please clearly state the hypotheses, carry out the test and state your conclusion for the tests listed below....

1. If two samples are drawn independently from the same population, then the sample means will be the same. true or false? 2. If two samples are drawn independently from the same population, then their sample standard deviations will be the same. true or false? 3. You can find below the results from Tukey's Honestly Significant Difference procedure with familywise significance level 0.05 for the agricultural experiment above. Which of the following can be concluded at this level? diff lwr...

A study was conducted on the number of hours slept by men and women. A sample of 18 men slept an average of 6.1 hours a day with a sample standard deviation of 2.1 hours, whereas a sample of 21 women slept an average of 6.4 hours a day with a sample standard deviation of 1.7 hours. Use a 0.05 significance level to test the claim that the average number of hours that there is a difference between the average...

777 We selected a random sample of n = 50 male adults. The sample men produced an average of x = 542 grams of fat per day with a standard deviation of s = 13.6 grams of fat per day. Based on this sample, construct a 95% confidence interval for the mean daily production of fat for the men. Then find 99% CI and compare to the 95% CI.

A random sample of 400 men and 400 women was randomly selected and asked whether they planned to attend a concert in the next month. The results are listed below. Perform a homogeneity of proportions test to test the claim that the proportion of men who plan to attend a concert in the next month is the same as the proportion of women who plan to attend a concert in the next month. Use α = 0.04. men women plan...

Twenty-five volunteer athletes participated in a study of cross-disciplinary athletic abilities. The group comprised athletes from football, baseball, water polo, volleyball, and soccer. None had ever played organized basketball, but did acknowledge interest and some social participation in the game. Height (inches), weight (pounds), and speed in the 100-yard dash (seconds) were recorded for each subject. The basketball test consisted of the number of field goals that could be made in a 60-min. period. The data are given in Athlete.jmp...
