Answer:
No, the population of people is poorly represented with this low sample size. 150 would better represent the population as a whole. 42 people would want to play on Rolling Meadows. (according to the previous data)
Step-by-step explanation:
Most likely this small sample size is too small to gain sufficient data from the whole population. If he were to survey a larger sample of people, he would overall better represent the population as a whole. The percentage of people who would prefer Rolling Meadows in the first sample was 28% (7/25). So just multiply 150 times .28 and get 42. 42 people would want to play on Rolling Meadows.
Answer:
a. (1,2), b. (1, 0)
Step-by-step explanation:

b.
Your answer is d :)
the slash means to divide
5 = 0.05w
5 / 0.05 = w
100 = w........5 is 5% of 100
Let x = number that sell for $18 each
Then, 200 - x = number that sell for $33 each
18x + 33(200 - x) = 4800
18x + 6600 - 33x = 4800
-15x = -1800
x = 120
There were 120 racquets selling for $18 each and 80 racquets selling for $33 each.
