Answer:
to compare the amount of coffee sold at the two coffee shops, we need to find the measure of center that is most appropriate for each data set.
for coffee ground, we can calculate the mean by adding up all the values and dividing by the total number of values:
mean = (1.5 + 20 + 3.5 + 12 + 2 + 5 + 11 + 7 + 2.5 + 9.5 + 3 + 5) / 12 = 5
the median for coffee ground can be found by arranging the data in order and finding the middle value.
arranging the data in order:
1.5, 2, 2.5, 3, 3.5, 5, 7, 9.5, 11, 12, 20
median = 5
for wide awake, we can also calculate the mean by adding up all the values and dividing by the total number of values:
mean = (2.5 + 10 + 4 + 18 + 4 + 3 + 6.5 + 15 + 6 + 5 + 2.5) / 11 = 6
the median for wide awake can be found by arranging the data in order and finding the middle value.
arranging the data in order:
2.5, 3, 4, 4, 5, 6, 6.5, 10, 15, 18
median = 4.5
comparing the two measures of center, we see that coffee ground has a mean value of 5 gallons, while wide awake has a mean value of about 6 gallons. however, the median for wide awake is 4.5 gallons, which is higher than the median for coffee ground at 5 gallons.
based on these calculations, we can conclude that wide awake typically sells more coffee per hour than coffee ground.
