To find the mean number of gallons of milk consumed last month, we need to calculate the sum of the gallons of milk and divide it by the number of families.
The sum of the gallons of milk consumed for the given families is:
(2 * 0) + (10 * 4) + (14 * 7) = 0 + 40 + 98 = 138
The number of families is:
2 + 10 + 14 = 26
To find the mean, we divide the sum by the number of families:
Mean = 138 / 26 = 5.31 (rounded to one decimal place)
Therefore, the mean number of gallons of milk consumed last month by these families is approximately 5.31 gallons.
A marketing research company records the consumer habits of a sample of 26 families from a certain community the table below summarizes the number of gallons of milk consume by these families during the last month
