A science teacher records the number of hours of sunshine over a 7 day period. The recorded hours are: 5, 6, 7, 8, 7, 6, 5. What is the average (mean) hours of sunshine per day for this period?

Step 1 ：Step 1: Add all the recorded hours together: \(5+6+7+8+7+6+5 = 44\) hours

Step 2 ：Step 2: The number of recorded days is 7

Step 3 ：Step 3: To find the average (mean), divide the total hours by the number of days: \(\frac{44}{7} = 6.28\) hours
