Answer:
Group by buckets and use that information to make your histogram.
Step-by-step explanation:
When you make a histogram you need to group elements into buckets, and out of those buckets make your histograms. You could for example take the mean or the median of groups and out of that information make the histogram. That is your decision.
For example that you have
JM 85
JM 73
so the mean between 85 and 73 is 79 , so in your histogram the height of JM would be 79.
To summarize, you group by buckets and use that information to make your histogram.
Answer:
How can you reduce the variability of a statistic? By taking a larger sample. Larger samples give smaller spread. Also by better design, such as stratified sampling. What effect does the size of the population have on the variability (spread) of a statistic?

7x100=700cm
Answer:
B
Step-by-step explanation:
If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.
2.5 = 3
5.5 x
cross multiply
16.5=2.5x
and divide
16.5/2.5 and you get your answer
Distribute on the left
217+111x-185=-4
Combine like terms
111x+32=-4
Sybtract 32 from both sides
111x=-36
Divide both sides by 111
x= -36/111
x=-12/37
Final answer: x=-12/37
