Answer:
- See below
Step-by-step explanation:
Given prices:
- $75, $120, $120, $145, $150, $150, $150, $175, $175, $200, $225, $275
a) Find the mean:
- (75 + 2*120 + 145 + 3*150+ 2*175 + 200 + 225 + 275)/12 = $163.33
b) Find the median
- The both middle numbers are $150, so it is the median
c) Find the mode:
- The most repeated price is $150 (3 times repeated)
d) Find the range:
- $275 - $75 = $200
