Answer:
4th one
Step-by-step explanation:
Your answer should be 7/12
Answer:
The first set 4 , 6 , 6 , 8
The second set 2 , 6 , 6 , 10
Step-by-step explanation:
Mean is the average of the values in a set. This can be found by summing all the numbers and dividing by the total number. The median is the middle number when the values are listed in order of increasing size. The mode is the number(s) that appear the most often in the set.
The first set 4 , 6 , 6 , 8
mean = (4 + 6 + 6 + 8 )/4 = 6
median = (6+6)/2 = 6
Mode = 6
The second set 2 , 6 , 6 , 10
mean = (2 + 6 + 6 + 10)/4 = 6
median = (6+6)/2 = 6
Mode = 6
Unfortunately, I don’t knooow :(
The mean of the data is 11
now we find the difference between the mean and each number
1, 2, 3, 0.5, 0.25, 1.25, 1.
now we square the numbers
1, 4, 9, 0.25, 0.0625, 1.
now we find the mean of the new numbers
which is 2.1875
2.1875 is your standard deviation.
