Answer 2

Mean = 50

Explanation:

Step 1: Write the mean formula

Mean = sum of data/ total number of data

Step 2: Calculate the sum of data

35 + 40 + 45 +50 + 55 + 60 + 65 = 350

Step 3: Find the total number of data

Total number of data = 7

Step 4: Calculate the mean

Mean = sum of data/ total number of data

Mean = 350/7

Mean = 50

Therefore, the mean of this data is 50.
