Answer:
87.08% percentage of families spend more than $4000 annually on food and drink
Step-by-step explanation:
Given -
average annual expenditure on food and drink for all families is $5700
Mean
= 5700
standard deviation
= 1500
Let X be the no of families spend annually on food and drink
percentage of families spend more than $4000 annually on food and drink =
= ![P(\frac{X - \nu }{\sigma }> \frac{ 4000 - 5700}{1500})](https://tex.z-dn.net/?f=P%28%5Cfrac%7BX%20-%20%5Cnu%20%7D%7B%5Csigma%20%7D%3E%20%5Cfrac%7B%204000%20-%205700%7D%7B1500%7D%29)
=
Using ![(Z = \frac{X - \nu }{\sigma })](https://tex.z-dn.net/?f=%28Z%20%3D%20%5Cfrac%7BX%20-%20%5Cnu%20%7D%7B%5Csigma%20%7D%29)
= 1 - ![P(Z](https://tex.z-dn.net/?f=P%28Z%20%3C-%201.13%29)
= 1 - .1292
= .8708
= 87.08%
