[0,1] could not be used to represent a probability.
Answer:
w<-84
Step-by-step explanation:
solved the equation
from least to greatest: 0.85, 8/9 (0.88 as a decimal), 0.93
We can set this up as a proportion.
Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

where d is the doctors surveyed.
Cross multiply.
2d = 4000
d=2000
2000 doctors were surveyed.
