Answer:
d. None of the above.
Step-by-step explanation:
<em>a. By the law of large numbers, it would again be 46%.
</em>
FALSE. This proportion (46%) is a sample statistic, that can or can not be repeated in another sample.
<em>b. By the law of large numbers, the smaller (second) survey will certainly produce a sample proportion farther from the true population proportion than the larger (first) survey.
</em>
FALSE. Smaller samples will produce wider confidence intervals for the estimation of the population proportion, but larger samples does not necessarily gives us better point estimations of the true proportion. A small sample can be closer to the true proportion than a large sample, although is less probable.
<em>c. The proportion computed from the sample of 5000 people would be more accurate because smaller samples tend to be more homogeneous than larger samples.
</em>
FALSE. There is no evidence to claim that smaller samples are more homogeneous.
<em>d. None of the above.</em> TRUE

Answer:
The correct answer is D. 2/11.
Step-by-step explanation:
To determine what is the probability of rolling a number less than or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6, the following calculation should be performed:
6 + 1 = 7
6 + 2 = 8
2/11 = X
Therefore, the probability of rolling a number less than
or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6, is 2/11.
18.64 divided by 2 is the cost for 2 pounds
so 9.32 is 2 pounds plus 18.64 for 4 pounds
$27.96 for 6 pounds
Answer:
V = 175 yd^3
Step-by-step explanation:
V = B*h
The base is the area of the triangle
B = 1/2 (5*7) = 35/2
so
V = 35/2 * 10
V = 175 yd^3
