Answer:
Step-by-step explanation:
We need to check each u value to say if each one is correct...
8
u - 27
when u = 33
8
33 - 27
8
6
and it's true!
So, 33 is solution
when u = 39
8
39 - 27
8
12
It isn't true. No solution!
When u = 31
8
31 - 27
8
4
It's true and it also is a solution.
when u = 35
8
35 - 27
8
8
it's true and it also is a solution.
In a normal distribution, the median is the same as the mean (25.3). The first quartile is the value of

such that

You have

For the standard normal distribution, the first quartile is about

, and by symmetry the third quartile would be

. In terms of the MCAT score distribution, these values are


The interquartile range (IQR) is just the difference between the two quartiles, so the IQR is about 8.8.
The central 80% of the scores have z-scores

such that

That leaves 10% on either side of this range, which means

You have

Converting to MCAT scores,


So the interval that contains the central 80% is

(give or take).
Answer: 
Step-by-step explanation:

There are 8 red and 4 blue beads
Three beads were taken from the box
(i)No of ways of choosing three red beads out of 12 beads is 
Total no of ways 
Probability is

(ii)atleast two beads refers to minimum two beads
There can be two possibilities (2B,1 R), (3B, 0R)
