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
Number of family/Gallon of milk
2 /0
10 /4
14 /7
for these families what is the mean number of gallons of milk consumed last month round your answer to at least one decimal place
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.
To find the mean number of gallons of milk consumed by the 26 families, we need to calculate the sum of all the gallons of milk consumed and then divide it by the total number of families.
Let's calculate it step by step:
1. Multiply the number of families by the number of gallons of milk consumed for each family:
2 * 0 + 10 * 4 + 14 * 7 = 0 + 40 + 98 = 138
2. Divide the sum by the total number of families:
138 / 26 = 5.3077 (rounded to at least one decimal place)
Therefore, the mean number of gallons of milk consumed last month by these families is approximately 5.3 gallons.
