Yes, since 3 times 1.5 is 4 and 2 times 1.5 is 3.
In first trails there are 3 cups of peanuts mixed with 2 cups of raisins.
Therefore ratio of peanut to raisins is
For second trail 4.5 cup of peanuts mixed with 3 cups of raisins
Answer:
Yes
Step-by-step explanation:
First, we need to find how many cars out of the entire fleet fail the test
4/32 = x/150
Cross multiply to find x
32x = 150(4)
32x = 600
32x/32 = 600/32
x = 18.75
I'll round it to 19. So 19 out of 150 cars fail the test. Find the percentage of this and compare it to the 30% estimate
19 /150 = 0.127
0.127(100) = 12.7%
12.7% is obviously lower than 30% so yes it is strong evidence the percentage of the fleet out of compliance is different from their initial thought
