the values of ta/2 and Za/2 when the sample<br />
2. Question : If the population proportion is .4<br />
with a sample size of 20, then is this sample large enough so that<br />
the sampling distribution of is a normal distribution.<br />
3. Question : For non-normal populations, as<br />
the sample size (n) _________, the distribution of sample means<br />
approaches a/an __________ distribution.<br />
4. Question : As the sample size ________the<br />
variation of the sampling distribution of ___________.<br />
5. Question : Assuming the same value of a, as<br />
the sample size increases, the value of ta/2 approaches the value of<br />
Za/2.
6. Question : If the sampled population has<br />
mean 48 and standard deviation 16, then the mean and the standard<br />
deviation for the sampling distribution of for n = 16 are<br />
7. Question : The sampling distribution of x<br />
bar must be a normal distribution with a mean 0 and standard<br />
deviation 1.<br />
8. Question : As our sample standard deviation<br />
increases when all other parts of the confidence interval stay the<br />
same, then the confidence interval will become:<br />
9. Question : When the sample size and sample<br />
standard deviation remain the same, a 99% confidence interval for<br />
a population mean, µ will be _____ the 95% confidence interval<br />
for µ.<br />
10. Question : A manufacturing company<br />
measures the weight of boxes before shipping them to the<br />
customers. If the box weights have a population mean and standard<br />
deviation of 90 lbs and 24 lbs respectively, then, based on a sample<br />
size of 36 boxes, the probability that the average weight of the<br />
boxes will be less than 84 lbs is
