<PRE><B>Question 1087372</B>
use the normal distribution 68-95-99.7 rule
:
68% of the values are 1 standard deviation around the mean (44-3.2, 44+3.2) = (40.8, 47.2) so I is false
:
95% of the values are within 2 standard deviations around the mean (44-6.4, 44+6.4) = (37.6, 50.4), 95 - 68 = 27, 27/2 = 13.5, so II is true
:
2.5% greater than 50.4 and 2.5% less than 37.6 = 5%, so III is true
:
