Answer:
Since they use random sampling then we can conclude that the two estimators would be unbiased of the real parameter.
So then the best answer would be:
c. The sample proportion, ^p, in either proposal is equally likely to be close to the true population proportion, p, since the sampling is random.
Step-by-step explanation:
For this case we have a first sample size and from this sample we have people who anwswer yes and the estimated proportion of yes is given by:
And let a second sample size and from this sample we have people who anwswer yes and the estimated proportion of yes is given by:
For this case we know that the true proportion is

Answer:
We need to sell 10 candy bars to break even.
Step-by-step explanation:
<em>The cost price of each candy bar is $0.6.</em>
<em>The shipping charges for one time is $9.</em>
Let "n" be the total number of candy bars bought.
Thus, the total amount spent by us is,
=
The selling price of each candy bar is $1.5
The total amount earned by selling all n candy bars is,
=
In order to break even, the profit should be equal to the total cost price.
=
=
=
A.) Jill:$25+10h Kelly:$18+14h
B.)25+10h+18+14h
25+18+10h+14h
43+24h
The company will pay <u>43+24h </u> for both Jill and Kelly to work on their project.
1a. Jill will make $125 and Kelly will make $158.
Answer:
Step-by-step explanation:
(2+10)/2 = 12/2= 6
(2+8)/2 = 10/2= 5
