Q. 98.6,99.0,98.9,98.3,98.7 98.6,99.0,98.9,98.3,98.7 \newlineWhat is the mean of the list of numbers?
  1. Add numbers and divide: To find the mean of a list of numbers, we add up all the numbers and then divide by the number of items in the list.\newlineCalculation: 98.6+99.0+98.9+98.3+98.798.6 + 99.0 + 98.9 + 98.3 + 98.7
  2. Calculate sum: Adding the numbers: 98.6+99.0+98.9+98.3+98.7=493.598.6 + 99.0 + 98.9 + 98.3 + 98.7 = 493.5
  3. Count items in list: Count the number of items in the list to divide the sum by.\newlineThere are 55 numbers in the list.
  4. Find the mean: Divide the sum by the number of items to find the mean.\newlineCalculation: 493.5/5=98.7493.5 / 5 = 98.7
