Kindly check explanation
Explanation:
A.)
From the histogram, the number of runners who made a certain range of Runtime can be easily deduced on the y-axis of the histogram, which isn't possible on the boxplot.
Summary statistic such as lower quartile, median and upper quartile statistics including outliers can be deduced easily from the boxplot.
B.)
Bimodal distribution occurs when two different groups or class have the highest number of values in a distribution.
C.)
The distribution of marathon times for men is fairly normally distributed while that if women is skewed.
The minimum and maximum values in the women's distribution is greater than the minimum and maximum values in the men's distribution.

Answer:
Ans. He must save during each of the following 10 years, at the end of each year $32,452.
Explanation:
Hi, in order to find the amount of money that he should have in ten years so he can receive an annual payment of $65,156 for 25 more years (24 payments), we need to bring to present value all 24 payments to year 10. Let me show you the formula.
Where:
A= $65,156
n= 24
r= 0.08
Therefore the present value in year 10 is:
So that is our present value in year 10, or to put it in other words, our future value (if we look at it from year 0). Now we need to find the annuity (amount to save) that with account for $686,012, plus that $100,000 that he already has saved.
Every should look like this.
And we solve this equation for "A".
Best of luck.
