(All units are 1000 cells/ Using Chebyshev's theorem what is known about the percentage of women with platelet counts that are within 2 standard de iations of the mean? What are the minimum and maximum possible platelet counts that are within 2 standard deviations of the mean? EEB Click the icon to view the table of platelet counts Using Chebyshev's theorem, what is known about the percentage of women with platelet counts that are within 2 standard deviations of the mean? ents At least 75 % of women have platelet counts within 2 standard deviations of the mean (Round to the nearest integer as needed) What are the minimum and maximum possible platelet counts that are within 2 standard deviations of the mean? The minimum possible platelet count within 2 standard deviations of the mean isThe maximum possible platelet count within 2 standard deviations of the mean is (Type integers or decimals rounded to one decimal place as needed) tents Enter your answer in the edit fields and then click Check Answer All parts showing n 28 (1/1) Question 25 (1/1) stion 26 (1/1) A 09/22/2018 here to searchExplanation / Answer
Answer:
Two standard deviation limits are ( µ-2*sd, µ+2*sd)
Minimum possible platelet count within 2 standard deviations of the mean is 255.0-2*65.2
= 124.6
Maximum possible platelet count within 2 standard deviations of the mean is 255.0+2*65.2
= 385.4
