- Suppose that household income in a state is distributed Normally with mean $60,000/year and standard deviation $10,000. What percentage of households have an income greater than $100,000?Supposed a number of students are added to an original group of students where all of whose ages are equal to the mean of age of original group. The standard deviation will?Mensa is an international high IQ society that accepts into its membership only those who score within the top 2% of the population on an approved intelligence test. Suppose that the scores on a Mensa-approved test are normally distributed with a population mean of 240 and standard deviation of 30. What is the minimum score on this test that would qualify one for Mensa membership?
- At a certain excavation site, archaeological studies have used the method of tree-ring dating in an effort to determine when people lived in there. Wood from several excavations gave a mean of (year) 1305 with a standard deviation of 22 years. The distribution of dates was more or less mound-shaped and symmetrical about the mean. Use the empirical rule to estimate a range of years centered about the mean in which about 68.3% of the data (tree-ring dates) will be found. Group of answer choices from 1239 to 1283 from 1305 to 1349 from 1239 to 1327 from 1327 to 1371 from 1283 to 1327Suppose the systolic blood pressure (in mm) of adult males has an approximately normal distribution with mean μ =125 and standard deviation σ =14.

- Among n=15 randomly selected participants of a hypothetical study, cholesterol was measured at Exam 1 and Exam 2. The mean difference in cholesterol between the two exams was -15.5 units and the standard deviation was 22.8 units. Differences were computed by subtracting the Exam 1 from Exam 2 value. Is there a statistically significant difference in mean cholesterol measured at Exam 1 and Exam 2 of the study?The sociologist finds that for a certain population, the mean number of years of educations is 13.2 years witha standard deviation of 3.04 years.
