This is a distribution of how much money was spent per week

This is a distribution of how much money was spent per week for a random sample of households in 2003

The Government says that household spending per week has gone down considerably in 2007.
What kind of graphical evidence would help me determine that there has been indeed a decrease in spending.

Select one:

a. The histogram will not help see a change even if it is very drastic.

b. The histogram for spending in 2007 would have to be far enought on the right hand side of the histogram for 2003

c. The histogram for 2007 would have to be skewed left

d. The histogram for spending in 2007 would have to be far enough on the left hand side of the histogram for 2003

Solution

elect one:

a. The histogram will not help see a change even if it is very drastic.

b. The histogram for spending in 2007 would have to be far enought on the right hand side of the histogram for 2003

c. The histogram for 2007 would have to be skewed left

d. The histogram for spending in 2007 would have to be far enough on the left hand side of the histogram for 2003

Option D is the correct answer if the histogram of 2007 in the same scale and far enough on the left hand side of the histogram for 2003
