Accepted Answer

To find the median, first, arrange the data in ascending order: 11, 11, 12, 12, 14, 15, 17, 17, 17, 20, 20. The median is the middle number, which is 15, since there are 11 numbers in total.

Question 2

The table shows the life expectancy in years of the G8 countries (Datablog, Guardian.co.uk, July 8 2009).What is the mean life expectancy of the eight countries?

Question 3

The table shows the GDP per capita (in US $s) of the G8 countries (Datablog, Guardian.co.uk, July 8 2009).What is the mean GDP per capita of the eight countries?

Accepted Answer

To find the mean GDP per capita of the eight countries, you would add together the GDP per capita of all eight countries and then divide by 8. The correct answer would depend on the specific GDP per capita values provided for each of the G8 countries, which are not listed here. However, given the options, the mean GDP per capita is most likely in the range of tens of thousands of dollars, making option B ($35,252) a plausible average value.

Question 9

A data set contains only two values.The larger of the two values is 25.If the range is 12, what is the median value in the data set?

Accepted Answer

The range of a data set is the difference between the largest and smallest values. Given the range is 12 and the largest value is 25, the smallest value must be 25 - 12 = 13. The median of a data set with only two values is the average of those two values. Therefore, the median is (25 + 13) / 2 = 38 / 2 = 19.

Question 10

For a sample of 10 days, Harkin Research recorded the number of visitors to Tilton.com's website.Compute the mean number of visitors per day. 100, 100, 106, 93, 89, 95, 97, 181, 99, 100

Question 11

Below is a list of shipping costs quoted by six online retailers for the same item.Compute the median shipping cost. $3.00 $2.84 $2.40 $3.02 $2.80 $2.51

Accepted Answer

To find the median, first arrange the shipping costs in ascending order: $2.40, $2.51, $2.80, $2.84, $3.00, $3.02. Since there are six numbers, the median will be the average of the third and fourth numbers: ($2.80 + $2.84) / 2 = $2.82.

Question 12

The number of US solar energy companies that applied for special tax credits in each of the past 11 months, according to a recent study, is shown below.Determine the mean for the data. 14, 17, 12, 11, 17, 20, 11, 12, 15, 17, 20

Accepted Answer

The answer of The number of US solar energy companies...

Question 13

The closing share price for G.E.stock over the past seven days is shown below.Compute the range for this data. 112, 115, 111, 116, 116, 116, 112

Accepted Answer

The range is the difference between the highest and lowest values in a data set. In this case, the highest value is 116 and the lowest value is 111, so the range is 116 - 111 = 5.

Question 14

Below is a list of shipping costs quoted by six online retailers for the same item.Compute the average shipping cost. $3.00 $2.84 $2.40 $3.02 $2.80 $2.51

Accepted Answer

To find the average shipping cost, add all the shipping costs together and then divide by the number of retailers. The total shipping cost is $3.00 + $2.84 + $2.40 + $3.02 + $2.80 + $2.51 = $16.57. Dividing this total by 6 (the number of retailers) gives an average shipping cost of $16.57 / 6 = $2.76.

Question 15

Below is a list of shipping costs quoted by six online retailers for the same item.Compute the standard deviation of the shipping cost data.Treat the data as a population. $3.00 $2.84 $2.40 $3.02 $2.80 $2.51
