Answer:
Mean = 50
Step-by-step explanation:
<em>Step 1: Write the mean formula</em>
Mean = sum of data/ total number of data
<em>Step 2: Calculate the sum of data</em>
35 + 40 + 45 +50 + 55 + 60 + 65 = 350
<em>Step 3: Find the total number of data</em>
Total number of data = 7
<em>Step 4: Calculate the mean</em>
Mean = sum of data/ total number of data
Mean = 350/7
Mean = 50
Therefore, the mean of this data is 50.
