The interquartile range (IQR) is 15.
To find the IQR, you must:
1) Find the median
2) Split the data set in two at the median.
3) Find the medians from both the groups you made in Step 2
4) Label the smaller one Quartile 1 and the larger one Quartile 3 (Hint: The median is Quartile 2)
5) Subtract: Quartile 3 - Quartile 1
Answer:
B) The scale on the y-axis could be changed to 25–40.
The answer to the question
Answer: Option B is correct
The expression to estimate the population of the country in 2005 is given by

Step-by-step explanation:
Since we have given that
In 1985, there was population of 145 millions.
Similarly,
In 1995, there was a population of 190 million .
Use the formula,

where A denotes the initial population and t denotes the number of years.
So, the expression becomes

∵ time period between 1985 to 2005 is 20 years.
So we take t=20 years.
So, the expression to estimate the population of the country in 2005 is given by

Answer:
358.5 sq-in
