Answer:
z-score = 2.
Step-by-step explanation:
The z-score = (x - m) / d where x =the person's score, m = the mean and d = the standard deviation.
So we have (87-67)/10
= 2.
Answer:
the answer is 1.16 shirts
Step-by-step explanation:
the mean absolute deviation is found by finding the average of the difference between each data point and the mean of the data.
1st...find the mean of the data by adding all the numbers according to the data plotted and dividing the by the numbers listed; which in this case is 10
1 +2+ 2+ 3+ 3+ 3+ 4+ 4+ 5+ 6 = 3.3
mean is 3.3
then find the difference between the mean and each data point
Data Point = 1 2 2 3 3 3 4 4 5 6
Difference from mean = 2.3 1.3 1.3 0.3 0.3 0.3 0.7 0.7 1.7 2.7
Find the average of these differences by adding the (differences from Mean) by 10
<u>2.3 + 1.3 + 1.3 + 0.3 + 0.3 + 0.3 + 0.7 + 0.7 + 1.7 + 2.7</u>
10
the mean absolute deviations is 1.16 shirts
Answer:a
a
b
Step-by-step explanation:
From the question we told that
The stem plots for American League is
Here the first column is the tens while each digit in the in the second column is the unit of the first column
For example row 3 means
40 , 43, 49
The sample size is n = 14
Generally the median is mathematically represented as
Here K is the 
i.e 
From the stem plot the 7th term is 57
And
K is the 
i.e 
From the stem plot the 8th term is 58
Thus the median is
=>
The stem plots for National League is
Generally the mean is mathematically evaluated as
Answer:
3xy
Step-by-step explanation:
Answer:
-19
Step-by-step explanation:
When you subtract from a negative it becomes a bigger number in the negatives. Subtract from a negative is also kind of like adding the 2 numbers then making it negative.
<u>Example:</u>
-2 - 2 = -4
2+2=4 making it negative will give you the answer of -4
-9-10 is like 9+10 which equals 19. Making it negative will give you the answer of -19
