- A disease occurs in 1% of the population. A diagnostic test gives a positiveresult in: 99% of people with the disease;5% of people without the disease(false positive). A person receives a positive result;What is the probabilityof them having the disease, given a positive result?Thirty percent of hospital admissions for diabetic patients are related to problems with the kidneys. In a sample of 10 diabetic hospital admissions, what is the probability that none will be for a kidney problem? (Round to 4 digits, ex. 0.1234)Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 300 times and got 122 heads. We wish to find how significant is this evidence against equal probabilities. What is the sample proportion of heads? Round to 3 places. Heads do not make up half of the sample. Is this sample evidence that the probabilities of heads and tails are different?Take p to be the probability of getting heads in a spin of a penny. Which hypotheses do we want to test? H0: p = 0.5H0: p ≠ 0.5 H0: p = 0.5H0: p > 0.5 H0: p = 0.5H0: p < 0.5 H0: p ≠ 0.5H0: p = 0.5 Compute the z test statistic.z = Round to 2 places.
