Which statement about the data is true?
228, 251, 22, 206, 254, 288, 228, 242
a. both the mean and median are appropriate measures of center.
b. both the median and mode are appropriate measures of center. this is the right answer.
c. the mean, median, and mode are all appropriate measures of center.
d. the median is the only appropriate measure of center.

(B)

Step-by-step explanation:

The given data set is:

228, 251, 22, 206, 254, 288, 228, 242

Since, in the given data set, 22 is an outlier which will affect the mean of the data, thus mean cannot be used to measure the center of the data due to the presence of an outlier.

Also, the median is the central value which is used to measure the center of the given data set, thus median can be used to find the measures of center.

The mode can be calculated for qualitative data as well as for quantitative data and can also be used to find the measures of center.

Thus, option B is correct.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
