Answer:
48
Step-by-step explanation:
60% of 80 is 48
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
1 1/2 or 3/2 because 1/2 divided by 1/3 is equal to that
Answer:
B
Step-by-step explanation:
Take the expression in chunks:
>>
>>
>>
Note that 
. So
where the cyclic sum notation means
In other words, we take the sum over all possible cycles of the sequence of arguments to the summand. The second square-bracketed chunk reduces to
So to recap, we've reduced the starting expression to
>>
Finally, we have
Then distributing 
and rewriting to decode the message, we have
