Calculate the mean, median, mode, range, variance, and standard deviation of the sample. (Round all calculations except the mode to one decimal place; add a trailing zero as needed. Do not round the mode.) The mean is type your answer.. bpm. The median is type your answer.. bpm. The mode is type your answer. bpm. The range is 8 type your answer... bpm. The variance is type your answer. bpm squared. The standard deviation is type your answer. bpm. 9 10 7 1 point 11 Workers at a health care facility measure the blood pressure (in mm Hg) of every patient who visits. The graph below is a relative frequency histogram for the systolic blood pressure readings of every patient aged between 25 and 40 years who visited during 2017. The readings were recorded to the nearest whole number. Approximately what proportion of 12 these patients had a systolic blood pressure reading of between 110 and 139 mm Hg inclusive? (Enter your answer as a decimal rounded to two decimal places. Do not enter a percentage.) 13 Relative Frequency 14 15 0.35 0.30- Type here to search O 26 65OF Sunny 1:25 PM 10/12/2022Applications | RapidIdentity x _ Quizzes 2 * *Dashboard X + X - > C A learn.vocs.edu/courses/500264/external_tools/retrieve?display=full_width&url=https%3A%2F%2Fvccs.quiz-Iti-iad-prod.instructure.com%2FIti%2Flaunch%3Fmodule_session%... [ * @ G Return Submit O -7 20 1 point A certain company manufactures precision thermometers that are supposed to give readings of 0.00' C at the freezing point of water. Tests on a large sample of these thermometers reveal that some give readings above 0.00' C and some give readings below 0.00' C. Suppose thermometer readings are approximately normally distributed with mean thermometer 0.00 C with a standard deviation of 1.00'. What is the thermometer reading that separates the top 4% of readings from the rest? (Round your answer to two decimal 898 places; add trailing zeros as needed.) E 35 1 The thermometer reading that separates the top 4% of readings from the rest is 1.75 2 2 21 1 point 4 Assume that the red blood cell counts of women are approximately normally distributed with a mean of 4.577 million cells per microliter and a standard deviation of 0.382 million A cells per microliter. Approximately what percentage of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter? (Enter your answer as a 5 percentage rounded to one decimal place; add a trailing zero as needed.) 6 The percentage of women who have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter is |82.26 percent. 8 22 1 point O Before every flight, a pilot must verify that the total weight of the load aboard their aircraft is less than the maximum allowable load for that type of aircraft. Suppose a commercial aircraft can carry 39 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,513 lb. Suppose the pilot sees that the plane is full and all passengers 10 are adult men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,513 lb/39 passengers = 167 lb/passenger. Assuming that weights of adult men are normally distributed with a mean of 179.8 lb and a standard deviation of 37.6 lb, what is the probability that the aircraft is overloaded? (Round your answer to three decimal places; add trailing zeros as needed.) 11 P(aircraft is overloaded) = [OLProb]. 12 P[the aircraft is overloaded] = type your answer. 13 14 Submit 15 - Type here to search O E @ m 26 1:26 PM 65 F Sunny ~ [ 0 0 () 10/12/2022 21
