Listed below are costs (in dollars) of roundtrip flights between two cities. all flights involve one stop and a two-week stay.

find the coefficient of variation for each of the two sets of data, then compare the variation. 30 days in advance: 263 nbsp 253 nbsp 255 nbsp 240 nbsp 311 nbsp 296 nbsp 262 1 day in advance: 454 nbsp 603 nbsp 568 nbsp 946 nbsp 603 nbsp 1013 nbsp 568 the coefficient of variation for the prices of tickets purchased 30 days in advance is 948 68th st5. 9.5%. (round to one decimal place as needed.)

the coefficient of variation for the prices of tickets purchased 1 day in advance is 31.2 31.2%. (round to one decimal place as needed.) is there a difference in variation between the two data sets?

a. there is no significant difference in the variation.

b. the costs of tickets purchased 1 day in advance have less variation than the costs of tickets purchased 30 days in advance.

c. the costs of tickets purchased 30 days in advance have less variation than the costs of tickets purchased 1 day in advance.
