Sample 2 is a random sample from grades 11 and 12 and consists of the following scores: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.
Choose the following statements that correctly compare the two samples.
Check all that are true.
A). Sample 2 shows 11th and 12th grade students, on average, did better.
B) . Sample 1 has a higher probability than Sample 2.
C). The measure of center is the same for both samples.
D). Sample 1 shows 9th and 10th grade students, on average, did better.
E). Sample 2 has a higher median score than Sample 1.
Answer:
E)- Sample 2 has a higher median score than Sample 1.
Step-by-step explanation:
For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).
We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.
Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.
building?
A man of mass of 80 kg standing at the top of a tall building has 96000 J of G.P.E. so, the height of the building would be 122 m.
The gravitational potential energy is defined as the product of mass, acceleration due to gravity, and height.
PE = mgh
Given PE = 96000 J and m = 80 kg
PE = mgh
96000 J = (80 kg) (9.8 m/s²) h
h = 96000 / (80 kg) (9.8 m/s²)
h ≈ 122 m
Thus, The height is 122 m approximately.

Step-by-step explanation:
Gravitational potential energy is:
PE = mgh
Given PE = 96000 J and m = 80 kg:
96000 J = (80 kg) (9.8 m/s²) h
h ≈ 122 m
