Friday is a class field trip and all 32 students bring their lunch. Will themean for the whole week be greater than or less than the mean for Monday through Thursday? Find the new mean

Insufficient information.

To find out if the mean for the whole week will be greater or less than the mean for Monday through Thursday, we need to calculate the means for both situations.

Let's start by calculating the mean for Monday through Thursday.

Assuming there are 32 students in total and they bring lunch every day, we can find the mean as follows:

Mean for Monday through Thursday = Total lunch brought by students / Number of days

Since there are 32 students and 4 days, the total lunch brought by students for Monday through Thursday is 32 * 4 = 128.

Mean for Monday through Thursday = 128 / 4 = 32

Now, let's calculate the new mean for the whole week, including Friday's field trip.

Since all 32 students bring their lunch on Friday as well, the total lunch brought by students for the whole week is 128 (from Monday through Thursday) + 32 (from Friday) = 160.

Mean for the whole week = Total lunch brought by students / Number of days

Since there are 5 days in the whole week, the new mean for the whole week is 160 / 5 = 32.

Thus, the mean for the whole week is equal to the mean for Monday through Thursday.

Therefore, the mean for the whole week is neither greater nor less than the mean for Monday through Thursday; it is the same.

To find out if the mean for the whole week (including Friday's lunch) will be greater or less than the mean for Monday through Thursday, we need to compare the total amount of lunch brought for both cases.

Let's start by calculating the mean for Monday through Thursday:
1. Add up the total amount of lunch brought for those four days.
2. Divide the total by the number of days (4) to get the mean for Monday through Thursday.

Let's assume the total amount of lunch brought for Monday through Thursday is X.

To find the new mean (including Friday's lunch), we need to consider that all 32 students bring their lunch on Friday. So, the new total amount of lunch for the week would be X plus the amount of lunch brought on Friday.

To calculate the new mean for the whole week:
1. Add up X (the total amount of lunch brought for Monday through Thursday) and the lunch brought on Friday.
2. Divide the new total by the number of days in a week (5) to get the new mean.

By comparing the mean for Monday through Thursday with the new mean for the whole week, we can determine if the mean will be greater than or less than.
