Question

Weekly Grocery Expense For The Past 12 Weeks Determined A Man Expense Of $87.56 One Week Expense Of $74 Was Incorrectly Recorded As 47 Find The Correct Mean

Answer 1

Answer:

89.81

Step-by-step explanation:

Let the total sum of expenses be S for 12 weeks

s/12=87.56

s=1050.72

47 is recorded instead of 74 so we must add up 27 for correct mean

now 1077.72/12=89.81
