Use the 68-95-99.7 rule to find the following quantities:\tSuggest you make a drawing and label first”\ufffd\ta. \ufffd\u00a0\u00a0\u00a0 Percentage of scores less than 100\t\u00a0\tb. \ufffd\u00a0\u00a0\u00a0 Relative frequency of scores less than 120\t\u00a0\tc. \ufffd\u00a0\u00a0\u00a0 Percentage of scores less than 140\t\u00a0\td. \ufffd\u00a0\u00a0\u00a0 Percentage of scores less than 80\t\u00a0\te. \ufffd\u00a0\u00a0\u00a0 Relative frequency of scores less than 60\t\u00a0\tf. \ufffd\u00a0\u00a0\u00a0\u00a0 Percentage of scores greater than 120\t\u00a0\t2. \ufffd\u00a0\u00a0\u00a0 Assume the body temperatures of healthy adults are normally distributed with a mean of 98.20 \u00b0F and a standard deviation of 0.62 \u00b0F (based on data from the University of Maryland researchers).\ta. \ufffd\u00a0\u00a0\u00a0 If you have a body temperature of 99.00 \u00b0F, what is your percentile score?\t\u00a0\tb. \ufffd\u00a0\u00a0\u00a0 Convert 99.00 \u00b0F to a standard score (or a z-score).\t\u00a0\tc. \ufffd\u00a0\u00a0\u00a0 Is a body temperature of 99.00 \u00b0F unusual? Why or why not?\t\u00a0\td. \ufffd\u00a0\u00a0\u00a0 Fifty adults are randomly selected. What is the likelihood that the mean of their body temperatures is 97.98 \u00b0F or lower?\t\u00a0\te. \ufffd\u00a0\u00a0\u00a0 A person’s body temperature is found to be 101.00 \u00b0F. Is the result unusual? Why or why not? What should you conclude?\t\u00a0\tf. \ufffd\u00a0\u00a0\u00a0\u00a0 What body temperature is the 95th percentile?\t\u00a0\tg. \ufffd\u00a0\u00a0\u00a0 What body temperature is the 5th percentile?\t\u00a0\th. \ufffd\u00a0\u00a0\u00a0 Bellevue Hospital in New York City uses 100.6 \u00b0F as the lowest temperature considered to indicate a fever. What percentage of normal and healthy adults would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6 \u00b0F is appropriate?<\/p>\n","protected":false},"excerpt":{"rendered":"
