A researcher is studying two types of medication that both treat hives. 18 out of the random sample of 201 adults given medication A still had hives 30 minutes after taking the medication. 22 out of another random sample of 212 adults given medication B still had hives 30 minutes after taking the medication. Test to see if the proportion of people who still had hives after medicine A is less than the proportion of people who still had hives after medicine B. Use a 0.05 level of significance. The correct hypotheses are: O Ho: PA HA PA Ho: PA HA PA O Ho: PA HA PA = PB PB(claim) The p-value is: PB PB(claim) PB PB(claim) Since the level of significance is 0.05 the critical value is -1.645 (round to 3 places) The test statistic is: (round to 3 places)

Recent studies have shown that adult men suffer from high blood pressure at a lesser rate than do adult women. To test that claim, a research randomly selected 200 of each gender and tested their blood pressure. The results revealed that 49 of the men and 62 of the women suffered from high blood pressure. Can you conclude that the proportion of men with high blood pressure is less than the proportion of women? Use α = 0.05.
The largest cat in North America is the Jaguar, they can sometimes be seen in the mountains of southern Texas, Arizona and New Mexico, (and less recently southern California). The rate of observances by humans is about 3/20 years. Assume we don't get Trump's border wall which would isolate the US population from the rest, and presumably cut off their chance of breeding. Chances of seeing 5 or more separate Jaguars within 5 years is 0.0011. a. Your cameras also produce pictures of wolf sized canids, either wolves or coy-wolves in the same region (very different times). Each year your cameras catch about 40 of these animals and about 30 cougars and about 400 bear and 800 feral Hogs. Assume that these numbers are all population rates for poisson. Given your camera Network catches a non human large animal (and the above list is all of them): Out of 200 large non human animals what is the probabilty that between 80 and 150 are feral hogs?
An article published in the American Journal of Hypertension reported the results of a longitudinal study on blood pressure. Ten years ago, 51 out of 188 people evaluated were classified as having high blood pressure. This year, 63, out of 194 people evaluated were classified as having high blood pressure. Based on the results of this study, can one conclude that the proportion of people in the population with high blood pressure has increased in the last ten years? Use a = 0.05. I can't find the sign=a I hope someone will know what I am talking about.
.A new, miracle diabetes drug that diminishes major symptoms of diabetes has been approved by the FDA. Health care professionals and researchers believe that the new drug will prolong lifespan of diabetes patients. If the population is in steady state and the incidence is constant, what will the effect of this new drug be on the prevalence of diabetes in the population? Explain.
I need help figuring out how to determine the percentage of increase. For each of the following models, state what the expected value of Y is when X = 50. Also, state how the predicted value of Y changes when X increases by 5 units (i.e., a 10% increase). 1. Y = 73 + 10X X=50, y=73+10*50 = 573 Y = 573 Change = 50 units 2. lnY = 4.9 + 0.025X x = 50, y = exp(4.9 + 0.025*50) = 468.7 =exp(0.025*5)=1.13 units. Y = 468.7 Change = 1.13 units 3. Y = -632 + 328(lnX) X = 50, y=-632 + 328*(in50) = 651.1 = 328*In(5) = 527.9 Y = 651.1 Change = 527.9 units 4. lnY = 2.7 + 0.94(lnX) x=50, y=exp(2.7 + 0.94*In50) = 588.3 = exp (0.94*In5) = 4.54 Y = 588.3 Change = 4.54 units

A person with tuberculosis is given a chest x-ray. Four tuberculosis x-ray specialists examine each x-ray independently. If each specialist can detect tuberculosis 83% of the time when it is present, what is the probabilty that at least 1 of the specialists will detect a person positive.

You wish to test whether a particular drug manages to bring body temperature down. So, you conduct a pilot study where 47 people receive the drug, and 45 people receive a placebo. The body temperatures of patients from the treatment group are group 1 (variable X1); those from the placebo group are group 2 (variable X2). What is the research hypothesis? mu1 > mu2 mu1 ≠ mu2 mu1 < mu2 mu1 = mu2
