Fran would like to estimate the mean amount of time it takes people in her town to travel to work. The town's population is 150,

000 and about 90,000 of those are working adults.
Which statements are true?


Select each correct answer.


A. If she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group.


B. The population of working adults is too large for using a sample to estimate the mean of the entire group.


C. There is no way to infer the value of the mean. She must collect data for all 90,000 working adults and calculate the mean.


D. A larger sample of working adults will provide a better estimate of the true mean than a smaller sample.

There are multiple contradicting statements within this problem, as noted above.

When your finding x in algebra how do u know the answer is infinite?
faltersainse [42]
X is basically a variable. Now the thing is, that variables do not have a definite value, and that they can have an infinite range of values. While solving an equation in algebra, you don't know what your answer is going to be therefore, the answer could be infinite! :)
