the city library monitored the number of books checked out each day. books checked out what is the mean of the numbers?
Answer
Explanation:
Step1: Identify the data values
The number of books checked - out each day: 80 (Tuesday), 80 (Wednesday), 50 (Thursday), 60 (Friday), 50 (Saturday), 60 (Sunday), 40 (Monday).
Step2: Calculate the sum of the data values
$80 + 80+50 + 60+50+60+40=420$
Step3: Determine the number of data points
There are 7 days, so $n = 7$.
Step4: Calculate the mean
The mean $\bar{x}=\frac{\text{Sum of data values}}{\text{Number of data values}}=\frac{420}{7}=60$
Answer:
60
