Oral N-acetylcysteine (NAC) exerts a beneficial action in chronic bronchitis by reducing the number of exacerbations. Bontognali et al. [1] conducted a randomized, double-blind study to measure the effectiveness of NAC in the long-term treatment of patients with chronic bronchitis and mild airway obstruction. The response is the number of acute exacerbations per month. The mean value and standard deviation for both experimental and placebo group are given below: Sample size Placebo Mean Sample size 59 Standard Deviation 0.15 Standard Deviation 0.19 70 0.16 To test if there is a statistically significant differences between NAC and placebo in number of observed exacerbations, the author plans to conduct a hypothesis testing at 10% level of significance. Answer the following questions according to the study: NAC Mean 0.11

Use the 1odwing Wildlife: Coyotes A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be z = 2.05 years, with sample standard deviation 8 = 0.82 years (based on information from the book Coyotes: Biology, Behavior and Management by M. Bekoff, Academic Press). However, it is thought that the overall population mean age of coyotes is µ=1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use a = 0.01.

Question is in reference to the notes attached. Help appreciated, thanks
Systolic blood pressure in healthy adults has a normal distribution with mean of 112 mmHg and standard deviation of 10 mmHg. Outside what range of values would we flag patients as needing follow-up, assuming we want to flag patients whose systolic blood pressure was outside of 2 standard deviations? Examined as a diagnostic test, how would sensitivity and specificity of this test change if we start flagging blood pressure values outside of 1 standard deviation instead of 2?
only need letter answer, no work needed
How do I find the p-value?

*please help me with this problem.I need to get it right to complete my homework.* In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before- after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.9 and a standard deviation of 19.8. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? What is the confidence interval estimate of the population mean muu? _mg/dL < muu< _mg/dL
