Answer:
mean=5
Explanation:
To find the mean of a set of data, we add up all the values in the set and then divide by the number of values.
Adding up the values in the set, we get:
3 + 5 + 4 + 4 + 5 + 7 + 7 = 35
There are 7 values in the set, so we divide the sum by 7 to get the mean:
mean = sum of values / number of values
mean = 35 / 7
mean = 5
