A study concluded that among people with acertain virus, 99.3 % of tests conducted were(correctly) positive, while for people withoutthe virus, 97.7% of the tests were (correctly)negative. If 22 % of patients actually carry thevirus, what's the probability that a patienttesting negative is truly free of the virus?Three decimal places needed

A hypothesis test is executed with an alpha = 10% and Ho is rejected. Using the probability model (or frequentist) view of probability discussed in class, what is the probability that the statistical conclusion is wrong? If we executed the same hypothesis test (with an alpha of 10%) on different random samples of data 10,000 times, approximately how many times would it make the mistake of rejecting Ho when Ho is actually true in the population? Your answer should be an integer.
Physicians at a clinic gave what they thought were drugs to 960960 asthma, ulcer, and herpes patients. Although the doctors later learned that the drugs were really placebos, 5252 % of the patients reported an improved condition. Assume that if the placebo is ineffective, the probability of a patients condition improving is 0.490.49. For the hypotheses that the proportion of improving is 0.490.49 against that it is >0.49>0.49, find the p-value. p=p=

What is the probability that a student has a high IQ given that she is left-handed? High IQ Normal IQ Right-handed 190 1710 Left-handed 10 90
A test to determine whether a certain antibody is present is 99.7% effective. This means that the test will accurately come back negative if the antibody is not present (in the test subject) 99.7% of the time. The probability of a test coming back positive when the antibody is not present (a false positive) is 0.003. Suppose the test is given to seven randomly selected people who do not have the antibody. What is the probability that the test comes back negative for all sevenpeople? and what is the probability that the test comes back positive for at least one of the seven people?
A group of people were asked if life exists elsewhere in the galaxy. 209 responded "Yes", and 227 responded "No".

A survey showed that 75% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 10 adults are randomly selected, find the probability that at least 9 of them need correction for their eyesight. Is 9 a significantly high number of adults requiring eyesight correction? The probability that at least 9 of the 10 adults require eyesight correction is ____ (Round to three decimal places as needed) Is 9 a significantly high number of adults requiring eyesight correction? Note that a small probability is one that is less than 0.05. A. Yes, because the probability of this occurring is small. B. No, because the probability of this occurring is small. C.Yes, because the probability of this occurring is not small. D. No, because the probability of this occurring is not small.
