A random sample (Sample 2) of grades 11 and 12 showed scores of: 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.
What is the median of Sample 1?
What is the median of Sample 2?
The median of Sample 1 is 83.5 and median of Sample 2 is 82.5.
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A random sample (Sample 1) from grades 9 and 10 showed scores of:
84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.
Ascending order: 50, 50, 77, 78, 83, 84, 85, 88, 96, 99
The sample has an even number of scores, so the median is the average of the two middle scores:
(83 + 84)/2
= 83.5
Therefore, the median of Sample 1 is 83.5.
For sample 2, the data set is 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.
Ascending order of scores: 57, 62, 74, 78, 82, 83, 86, 90, 96, 97
The sample has an even number of scores,
so the median is the average of the two middle scores: (82 + 83)/2
= 82.5
Hence, the median of Sample 1 is 83.5 and median of Sample 2 is 82.5.

Answer:
?
Step-by-step explanation:
Answer:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60
Step-by-step explanation:
all numbers are multiples of 6, thus are divisible by 6
Answer:
6,12,18,24,30,36,42,48,54, and 60.
Step-by-step explanation:
To find this you can just keep on adding 6 to itself like this:
6+6=12 12+6=18 and so on,
Answer:
1.7 seconds, and
3.3 seconds
Step-by-step explanation:
We simply need to plug in 8 into h and solve for t:
Since cosine is negative in the 3rd quadrant as well, we need to figure out the 3rd quadrant equivalent of 2.13 radians.
First, π - 2.13 radians = 1.01 radians.
Then, we add 1.01 to π radians, so we get 4.15 radians
Solving from the last part, we have:
also, t = 3.30 seconds
*Note: we put the calculator mode in radians when solving
So, t = 1.7 seconds & 3.30 seconds
-2 1/8
-1 3/8
1 3/8
2 1/8
Answer: - 2 1/8
Step-by-step explanation: Lets first get common denominators of 8.
-7/4 = -14/8 (-7 x 2 = -14 and 4 x 2 = 8)
-14/8 - 3/8 = -17/8 or -2 1/8
Answer:
2 1/8.
Step-by-step explanation:
That is |-7/4| + 3/8
= 7/4 + 3/8
= `14/8 + 3/8
= 17/8
= 2 1/8.
