3a) The mean IQ of 200 patients in a psychiatric hospital is 91, with a variance of 16, and the distribution is highly negatively skewed. Between what two IQ scores would we expect to find at least 160 of the patients falling? b) If the distribution was mound-shaped and symmetrical, with the same mean and standard deviation as in part A, approximately how many patients would have IQ scores at or below the 5th percentile or above a score of 97? Answers: a) 82 to 100 b) 28.5 or 29

Suppose that the mean and standard deviation of plants height are 130 and 32, respectively, if a random sample of size 49 is slected from these plants, then the probability that their average height is more than 125 is closest to: O a. 0.20 O b.0.86 Oc. 0.26 O d. 0.14 O e. 0.74 Next page
Provide an original example of some practical case where we can use the normal distribution (e.g., IQ scores follow a normal distribution of probabilities with a mean IQ of 100 and a standard deviation of 15 IQ points.). Assign your numbers for mean 70 and standard deviation 30. Make sure 70 is about four times bigger than 30. Then select any number 90 below or above mean 70, but not too far from 70. Find following two probabilities: 1) P(x < a)2) P(x > a)Use the formula z = (a - μ)/σ to calculate your z-value. Please refer to the Appendix Table for the Standard Normal Distribution Hint: To find P(x>a) use formula: P(x>a) = 1 - P(x<a). Describe how to would find P( 65 < x < 25). Provide an original example to illustrate how to find such probabilities.
Suppose that the grades of Mathematics module is modeled well by a normal probability distribution with mean (170) and standard deviation (220). Let X be the random variable representing this distribution. Find two symmetric values “a” and “b” such that ??????????? [ a < ? < ? ] = 0.99 , where ?=−?
