Customers per day:
98, 87, 93, 82, 101, 99, 97, 97, 91
Find the mean to the nearest tenth:
[tex]\large\rm{Solution:}[/tex]
Mean = [tex] \tt \frac{sum \: of \: data}{number \: of \: data}[/tex]
[tex] \tt \frac{98 + 87 + 93 + 82 + 101 + 99 + 97 + 97 + 91}{9} = \frac{845}{9} = \green{93.89}[/tex]
Therefore, the mean is 93.89
