Answer #1

45. TRUE - If the outcomes of a random variable have high variability or it is more random, we will need more trials to ensure that the mean outcome is close to the expected value.
46. TRUE - The data collection is one of the important steps in statistical inferential procedures and if this step is done incorrectly, the outcome will be absurd.
47. FALSE - The margin of error only accounts for the random sampling variability. It does not take into account any other sources of error like people refusing to answer, measurement error etc.
48. TRUE - As we do more and more repititions, we eventually get closer to the expected value as averaging over many outcomes produce a stable result

    1-The answer is true or false a-Random errors arise from both measurement errors and sampling variation. True        False b-Sampling variability stems from inaccuracies in assessing the exposure and disease occurrence. True         False c-Just like bias and confounding, random errors are considered systematic errors. True     False d- In addition to the p-value, the confidence interval is another method for estimating the amount of random error in epidemiological studies. True     False

    Part I: Determine whether each of the following statements is TRUE or FALSE, and write a short explanation for your answer The mean and median are always equal to each other and can never be different. The median and mode must always be equal and can never be different. The expected value of a random variable is a weighted average of outcomes, where each outcome is weighted by its probability of occurrence. Regressions are used to estimate the relationship between...

    2. (2   True-False. Just say whether each statement is True or False – no need to justify your answer. 1. If the number of trials in the binomial distribution increases by 1 (and P equals .50), the probability of getting either of the most extreme possible outcomes (that is, 0 or N) is cut in half. 2. If the number of trials in the binomial distribution increases by 1 (and P does not equal .50), the probability of getting either of...

    True or False (1 point each) (Correct the ones that are false) The purpose of an interval estimate is to provide information about how close a point estimate, i.e. sample statistic, is to the population parameter. If the population standard deviation is unknown and cannot be estimated from historical data, an interval estimate for the population mean can be constructed by substituting the sample standard deviation and using the t distribution instead of the normal distribution. You cannot determine a...
