If the mean of a data set is 50 and there are 10 values, what is the total sum of the values?
Correct Answer: 500
Step 1: Understand that the mean is the average of a set of values.
Step 2: Know that the mean is calculated by dividing the total sum of the values by the number of values.
Step 3: In this case, the mean is given as 50.
Step 4: The number of values in the data set is given as 10.
Step 5: To find the total sum, use the formula: Total sum = Mean * Number of values.
Step 6: Substitute the values into the formula: Total sum = 50 * 10.
Step 7: Calculate the total sum: 50 * 10 = 500.
