Answer:
0.1655
Step-by-step explanation:
This is a binomial probability.
THe formula is:

Where n is the total number of people
r is how many we want (we want 1/3rd of 18 which is 6, r= 6)
p is probability of success (0.4)
Putting the information, we get:

Thus, the probability that exactly a third of the buyers would prefer brown is 0.1655

Answer:
no, the relationship is not proportional
Step-by-step explanation:
The table says Brianna crocheted 19 inches in 10 minutes. If the relation were proportional, Brianna would have crocheted 5×19 = 95 inches in 5×10 = 50 minutes. Her actual length is only 23 inches, so length is not proportional to time.
Answer:
1.) It is biased
2.) No
3.) Yes
4.) No
Step-by-step explanation:
1.) It is biased as it is predisposition to one particular outcome over another.
2.) No, because biased in research leads to unrepresentative outcomes as the estimates is predisposed to the left or to the right of the true values.
3.) Yes. Since the selection of shift has an equal probability of being chosen.
4.) No. The probability that the sample accurately reflects the efficiency of the workers, the standard should be 95%.
A) 43,000
10^3 is the same as 10,000
multiply 10,000 by 4.3=43,000
