If I want my estimate to be accurate, I want the error of pN to be small. How many people should I poll toguarantee the erpected squared error on PN is less than e? Suppose you want to find out how many people support Policy X. A standard polling approach is to just ask Nmany people whether or not they support Policy X, and take the fraction of people who say yes as an estimate ofthe probability that any one person supports the policy. Suppose that the probability someone supports the policyis p, which you do not know. Let pn be the number of people polled who supported the policy, divided by the totalnumber of people polled N.

Given that - Suppose you want to find out how many people support Policy X. A standard polling…

The scores on a test are normally distributed with a mean of 150 and a standard deviation of 30. Find the score that is 2 1/2 standard deviations above the mean.
When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain approximately 60% of his or her maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of one hundred 20-year-olds was taken, and the sample mean was found to be 107 bpm, with a standard deviation of 45 bpm. Researchers wonder if this is evidence to conclude that the expected level is actually lower than 120 bpm. To determine this, we test the following hypotheses: Ho: H= 120 versus H₂ μ< 120 Suppose the mean and standard deviation obtained were based on a sample of size 25 rather than 100.

You have developed an exam to measure knowledge of biology and administered it to a large number of people. On this exam, u= 85 and o = 10. You standardize the distribution so that the new mean and standard deviation are u = 50 and o = 5 If someone takes the exam and receives a score of 73 (before the score is transformed), what will this score be once it is transformed for the new (standardized) distribution?
How do we set an "alpha level" in science? How is this related to our comparison with a "p-value"?
