Two scores are equidistant from the Mean of 60. Between them there are 57.62% of all the scores. L is the lower score and U is the upper score. Find L and U. L = ________________ U = _______________
CALCULATING STANDARD DEVIATION The standard deviation is used to tell how far on average any data point is from the mean. The smaller the standard deviation, the closer the scores are on average to the mean, When the standard deviation is large, the scores are more widely spread out on average from the mean. The standard deviation is calculated to find the average distance from the mean. Practice Problem #1: Calculate the standard deviation of the following test data by hand. Use the chart below to record the steps. Test Scores: 22, 99, 102, 33, 57, 75, 100, 81, 62, 29 Mean: n: (Difference from the mean) (x – x)? Difference from the mean Test Score (x) (x- X) Sum of (Difference from the mean) E(x- X) → This is called variance. Sum of (Difference from the Mean) divided by degrees of freedom (n -1): E(x - x)? (п — 1) Final Step: Standard deviation = square root of what you just calculated (variance). E(x-x)? Standard deviation = (п-1)

Coming to School The time X it takes Mrs. Irvine to drive to work on a randomly selected day follows a distribution that is approximately Normal with mean 22 minutes and standard deviation 5.2 minutes (she is a Statistics teacher, after all): Once she parks in the back parking lot it takes her 4 more minutes to walk to her classroom. Let T = the total time it takes Mrs Irvine to reach her classroom on a randomly selected day, so T = X+4 Describe the shape, center, and variability of the probability distribution of T. Study habits Study habits are so important that Mrs. Irvine often considers implementing her own study at MNHS. Fortunately, the Survey of Study Habits and Attitudes is a psychological test that exists already. This test measures academic motivation and study habits_ The SSHA score F on a randomly selected female student at a large university has mean 120 and standard deviation 28, and the SSHA score M of a randomly selected male student at the university has mean 105 and…

A study examines the link between miscarriage and the use of painkillers during pregnancy. Scientists interviewed 1009 women soon after they got positive results from pregnancy tests about their use of painkillers around the time of conception or in the early weeks of pregnancy. The researchers then recorded which of the pregnancies was successfully carried to term. The results are in the table below. (NSAIDS refer to a class of painkillers that includes aspirin and ibuprofen.) Does there appear to be an association between having a miscarriage and the use of painkillers? Miscarriage No miscarriage Total NSAIDS 18 57 75 Acetaminophen 24 148 172 No painkiller 103 659 762 Total 145 864 1009 Table 1 Does the use of painkillers increase the risk of miscarriage?
