Question

Suppose that rada point average of undergrathathenstone university Hotels near but with mean of 251 and a standard deviation of 043 using the empirical rule, what percentage of the students seyado paint averages that are no more than 3.377 Prase do not round your answer

Answer 1

according to empirical rule , the percentage of students have grade point averages no more than 3.37 is = 97.5 %

[ explanation:-

the diagram showing data distribution :-

49. 1). 95. | 6 . 34). 3 4 ). 2. 5. 2, 35В О. 15 2:35. 13:52. ш-26 - 20 - | 2, 3Б. Е ш+ 20 ш+36 . ш ш +0

we have,

u= 2.51, 0 = 0.43

the z score for X=  3.37 is:-

-() (57-1351) - 2

the percentage of students have grade point averages no more than 3.37 is :-

= percentage of data that are lying below the value 2 sd above the mean

= (50+34+13.5) % (for ease see the diagram showing the data distribution and keep in mind that normal curve , is a symmetric curve)

=97.5 % ]
