The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable. Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.
A survey was conducted two years ago asking college students their top motivations for using a credit card. You think the distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a=0.10. 1. Determine the critical value, and the rejection region. 2. Calculate the test statistic.
The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 113, x = 12.4, and s = 6.63. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.) State the appropriate null and alternative hypotheses. O Ho: H = 15 H: u > 15 O Ho: H = 15 H: u < 15 Ο H: μ15 H:us 15 Ο Η: μ- 15 H: u = 15 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = p-value = State the conclusion in the problem context. O Reject the null hypothesis. There is sufficient evidence that average daily zinc intake falls below 15 mg/day. O Do not reject the null hypothesis. There is sufficient evidence that average daily zinc intake falls below 15 mg/day. O Do not reject the null hypothesis. There…
PM Wed Nov 3 Stats Home Insert Draw View 8). Studies have shown that drivers who use cell phones while operating a motor passenger vehicle increase their risk of an accident. To quantify this risk, the New England Journal of Medicine (January 2, 2014) reported on the risk of a crash (or near crash) for both novice and expert drivers when using a cell phone. In a sample of 371 cases of novices using a cell phone while driving, 24 resulted in a crash (or near crash). In a sample of 1,467 cases of experts using a cell phone while driving. 67 resulted in a crash (or near crash). a). Find a 93% confidence interval for p, the true crash risk (probability) for novice drivers, also indicating the ME value. Answer: ME = b). Find a 93% confidence interval for p, the true crash risk (probability) for expert drivers, also indicating the ME value. Answer: гр, ME =

Refer to the journal for the following items: A Case Series of Gastrointestinal Tuberculosis in Renal Transplant Patients Tuberculosis is a disease relatively frequent in renal transplant patients, presenting a wide variety of clinical manifestations, often involving various organs and potentially fatal. Gastrointestinal tuberculosis, although rare in the general population, is about 50 times more frequent in renal transplant patients. Intestinal tuberculosis has a very difficult investigational approach, requiring a high clinical suspicion for its diagnosis. Therapeutic options may be a problem in the context of an immunosuppressed patient, requiring adjustment of maintenance therapy. The authors report two cases of isolated gastro-intestinal tuberculosis in renal transplant recipients that illustrates the difficulty of making this diagnosis and a brief review of the literature on its clinical presentation, diagnosis, and therapeutic approach. Gastrointestinal tuberculosis among the…
According to Time Magazine (June 11, 2012), 33% of all cars sold in the United States are SUV's. Suppose a random sample of 500 recently sold cars shows that 145 are SUV's. is there enough evidence at the 1% alpha level, to conclude that the number of SUV's recently sold is less than 33%? 1. Develop a plan. State the type of test you will do, and why you will do that specific test. 2. State your steps List your given information: List your H, and H, H Write H, in words: H₂ Write H, in words Check your conditions 3. Document all steps used to find your answer Compute all of the values you will use with appropriate formulas or using appropriate technology 4. Determine whether or not to reject H and write a concluding statement in context of the problem.

2) Let X₁, X2, ..., Xn be a random sample from the pdf f(x;0) = 0xª−¹, 0≤x≤ 1,0 <0 < ∞. Find the MLE of 0 and show that its variance approaches 0 as n approaches ∞o.
Birth Weight Data Set 1 “Body Data” in Appendix B includes birth weights of 195 males, and the summary statistics are x = 3272.8 g and s = 660.2 g. Use a 0.01 significance level to test the claim that the population of birth weights of males is less than 3400 g.a. Assume that nothing is known about the prevalence of chickenpox. Use the critical value (Classic) method to solve hypothsis testing
