Answer:
10
Step-by-step explanation:
11, 13, 4, 9
In order to find the median we must first arrange the numbers in order (Least to greatest)
4, 9, 11, 13
If there is 2 numbers in the middle: the median is their average
If there is only one number in the middle, that number is the median.
Since there are two numbers (9 and 11) we have to take their average.
(9+11) / 2 = 20 / 2 = 10
The median is 10!
Answer:
<em>Your Interquartile range (IQR) would be 19.</em>
Step-by-step explanation:
-5, 1, 3, 7, 8, 10, 32, 36
Median: 7.5
Lower quartile: 2
Upper quartile: 21
Interquartile range: 21 - 2 = 19
#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
Considering the situation described, the hypothesis tested are given as follows:
- The null hypothesis is
- The alternative hypothesis is
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:
At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

The steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.
<h3>How to determine the steps you need to do to evaluate the expression</h3>
The expression is given as:
-5(-2)
The above expression represents the product of -5 and -2
This can be interpreted as:
- Removal of 5 groups of -2; to remove means negative
- Dragging zero pairs of 5 and 2 to the interactive window
Hence, the steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.
