- Please do not give solution in image format thanku One issue is that some patients experience side effects and have to discontinue treatment. It was estimated that 19% of patients receiving lnterleukin-2 plus vaccine developed an arrhythmia (irregular heartbeat) and had to discontinue treatment. Since the side effect was attributable to the vaccine, assume that the patients would continue to take lnterleukin-2 if arrhythmia developed but not the vaccine and that the probability of a positive response to treatment would be the same as group A (i.e., 6%). Suppose we have 10 patients who receive Interleukin- 2 plus vaccine of whom 2 develop arrhythmia and 8 do not. What is the probability that exactly 3 of the 10 patients will get a positive response to treatment?Please solve the following attached question and round as needed in parts a and b. In part b, options for H0 and H1 null and alternatives hypotheses are: There is no lack of fit for the model A linear model would fit the data better than a quadratic model A cubic model would fit the data better than a quadratic model An exponential model would fit the data better than a quadratic model There is a lack of fit for the modelA past survey claimed that at least 15% of sports activities per day.

- AttachedYou measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty? You make a 100 mL, 1 mM solution of glycine in water using a balancewith an uncertainty of 0.1 mg and a graduated cylinder with an uncertaintyof 1 mL. What is the concentration with uncertainty? Please use the formula I posted Thank you!Elaine is interested in determining if men are more satisfied in their jobs than women in the healthcare industry. She administers a job satisfaction questionnaire to 20 men and 20 women working in hospital administration. Her grouping variable is gender and dependent variable is job satisfaction. The job satisfaction scale consists of 8 items measured using a 5-point rating scale. A higher score on this scale would indicate high job satisfaction. The maximum score that can be obtained on the scale is 40. We can assume that job satisfaction scores are normally distributed. Use the appropriate T test with a significance level of 0.05 to test the hypothesis. Research Question Do the mean job satisfaction scores differ for men and women working in the hospital administration department? Hypothesis The mean job satisfaction scores do not differ for men and women working in the hospital administration department. Compute an independent sample t test on these data. Report…
