Answer:
Science students
When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =
406
SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
406 / 9 = 45.111

Answer:
0.973
Step-by-step explanation:
Given the following :
Population mean (μ) = 185
Standard deviation (σ) = 26.7
Sample mean (m) = 177.6
Sample size (n) = 48
P(m > 177.6)
Z = (m - μ) / σ/√n
Z = (177.6 - 185) / (26.7/√48)
Z = −1.920176
P( z > - 1.920) = 1 - p(z < - 1.92)
Using the z table :
1 - p(z < - 1.920) = 1 - 0.0274 = 0.9726
= 0.973
