Expert Solution

The following table is obtained:

Categories	Observed	Expected	(fo-fe)2/fe
Category 1	68	200*0.37=74	(68-74)2/74 = 0.486
Category 2	51	200*0.23=46	(51-46)2/46 = 0.543
Category 3	42	200*0.17=34	(42-34)2/34 = 1.882
Category 4	8	200*0.05=10	(8-10)2/10 = 0.4
Category 5	31	200*0.18=36	(31-36)2/36 = 0.694

Sum =	200	200	4.007

5) Conclusion

It is concluded that the null hypothesis Ho is not rejected. Therefore, there is NOT enough evidence to claim that

the percentage differ from those stated the chart at the α=0.05 significance level

A study is done to determine the effects of different forms of regular exercise on HDL levels in persons between the ages of 18 and 29. The forms of exercise observed were aerobic, weight training, and yoga. The participants HDL levels are measured after 8 weeks. Using multiple linear regression, the following regression line was created: HDL = 54.6-2.22(aerobic exercise)-1.75(weight training) Aerobic exercise is measured in hours. Weight training is a dichotomous (binary) outcome. 1=yes; 0=no Estimate the HDL level...

1.A study was done to determine whether there is a relationship between snoring and the risk of heart disease. Among 1,105 snorers in the study, 86 had heart disease, while only 29 of 1,379 nonsnorers had heart disease. (a)Determine a 95% confidence interval that estimates p1 − p2 = difference in proportions of snorers and nonsnorers who have heart disease. (Let p1 be the proportion of snorers and p2be the proportion of nonsnorers. Round your answers to three decimal places.)...

a study was done to determine if daily maximal-squat training had a positive effect on a 3 rep squat max compared to once per week high-intensity training men in their 20s. Twenty-four individuals were randomly selected from a large list of competitive weightlifters, all between 20 and 25 years old. Each of the men had been competing and training in weightlifting since the age of 16 and each could back-squat more than double their own bodyweight. The men each performed...
