Answer:
a) 0.437; b) 0.291
Step-by-step explanation:
For part a,
There are 280+210 = 490 people that are over 18 years old. Out of these, 119+95 = 214 purchase 2 pairs of jeans annually. This is
214/490 ≈ 0.437
For part b,
There are 87+69+74+11 = 241 people who purchase 3 or more pairs of jeans. There were a total of 220+290+280+210 = 1000 people; this means there were 759 people tho purchased fewer than 3 pairs of jeans.
Out of these, 21+74+126 = 221 were in the age group 12-18. This gives us
221/759 ≈ 0.291

2.52 / 0.6=4.2
150.88 / 4= 37.72
1.54 /7 = .22
8*6=48, 48/6=8, 48/8=6 :)
Mean is 94.
Add all of them and then divide with add numbers and medain
