Accepted Solution

A:

Answer:Total number of people who actually went to the spa from picture 2 are :61+12+59+73+122+41 = 368Percentage distribution over the week:Monday = 15% , number of people are [tex]0.15*368=55[/tex] (rounding to whole numbers)Tuesday = 7% , number of people are [tex]0.07*368=25[/tex]Wednesday = 15%, people are [tex]0.15*368=55[/tex]Thursday = 18%, people are [tex]0.18*368=66[/tex]Friday = 30% , people are [tex]0.3*368=110[/tex]Saturday = 15%, people are [tex]0.15*368=55[/tex]Total people as per picture 1 = 55+25+55+66+110+55 = 366Now, checking all the options the option that describes the situation will be option B - The data observed for Tuesday and Saturday do not fit the model. because there is a large difference in the number of people. In rest options, the difference is not very large. So, B is the best possible answer.
