53. Make a scatter plot relating the age to the percent of the persons budget spent on entertainment?
54. Also draw a line of best for Number 53?

Answer:
30 : 6.1 (place the point close to 6.0)
40 : 6.0 (place the point on 6.0 {up and down line}
50 : 5.4 (place the point almost in the middle of 5 and 6)
60: 5.0 (place the point directly on 5)
70 : 4.7 (place the point between 4 and 5, but closer to 5)
80 : 3.4 (place the point almost in the middle of 3 and 4)
the best fit of line should be a line that almost touches all the lines such as the picture I've sampled you
