Customer Question

(1.)Find the median of each set of numbers/ 1, 4, 9, 15, 25, 36. (2.) Find the mode of each set of numbers./41, 43, 56, 67, 69, 72/and 9, 8, 10, 9, 9, 10, 8. (3.) Statistics. A salesperson drove 238, 159, 87, 163, and 198 miles (mi) on a 5-day trip. What was the mean number of miles driven per day? (4.) Business and finance. The following scores were recorded on a 200-point final examination:
193, 185, 163, 186, 192, 135, 158, 174, 188, 172, 168, 183, 195, 165, 183.
(a) Find the mean final examination score.
(b) Find the median final examination score.
(c) Is the mean or median a more useful representative of the final examination scores? Write a brief paragraph justifying your response. (5.) Questions 5-10 are from the chart attached. Round answers to the nearest tenth or tenth of a percent.((a) What is the population of Europe in 2000?(510,000,000)
(b) What is the total area of Europe?(3,800 miles) (Compare the population per square mile in Asia to the population per square mile in North America for the year 2000.Asia 17,400-NA-9,400. What is the percent increase in the population for all six inhabited continents, excluding Asia, from 1950 to 2000. What was the percent increase in the population in South America from 1900 to
2000? (10. (a) What was the mean population of the six continents or land masses that were habitable in 2000?
(b) What was the mean population in 1950?
(c) What was the percent increase in the mean population from 1950 to 2000?

(1.)Find the median of each set of numbers/ 1, 4, 9, 15, 25, 36.

Median = middle number (or average of the two middle numbers):

= (9+15)/2

= 24/2

= 12

(2.) Find the mode of each set of numbers./41, 43, 56, 67, 69, 72/

mode = most common number(s) = none

and 9, 8, 10, 9, 9, 10, 8.

= 9 (since there are 3 of them)

(3.) Statistics. A salesperson drove 238, 159, 87, 163, and 198 miles (mi) on a 5-day trip. What was the mean number of miles driven per day?

mean = sum of the numbers / number of them

= (238+ 159+ 87+ 163+ 198) / 5

= 169 miles

(4.) Business and finance. The following scores were recorded on a 200-point final examination: 193, 185, 163, 186, 192, 135, 158, 174, 188, 172, 168, 183, 195, 165, 183. (a) Find the mean final examination score.

= 176 (b) Find the median final examination score.

= middle number

put them in order: 135, 158, 163, 165, 168, 172, 174, 183, 183, 185, 186, 188, 192, 193, 195

= 183

(c) Is the mean or median a more useful representative of the final examination scores? Write a brief paragraph justifying your response.

In this case, the median is a better representation. More than half the students scored above the mean, so it makes it seem like the scores are lower than they actually were, mainly because of the person who got a 135.

(5.) Questions 5-10 are from the chart attached. Round answers to the nearest tenth or tenth of a percent.((a) What is the population of Europe in 2000?(510,000,000) (b) What is the total area of Europe?(3,800 miles) (Compare the population per square mile in Asia to the population per square mile in North America for the year 2000.

pop per sq mile = population / square miles

Asia =(NNN) NNN-NNNN17400000

= 231.5

NA =NNN-NN-NNNN9400000

= 32.45

Asia's is much higher!

What is the percent increase in the population for all six inhabited continents, excluding Asia, from 1950 to 2000.

They are already rounded. That statement "round to the nearest tenth" was referring to the percentages that were listed in the other parts. I have rounded those as shown.
