BaLLatris [955]

Answer:

e. All of the reasons are correct.

Step-by-step explanation:

In most cases, studying all the population is impossible. In other cases, it is too expensive or time consuming.

A sample will give us, in most cases and combined with tools of statistical analysis (hypothesis testing or confidence intervals), enough information to make an unbiased estimation about the characteristic of the population we are studying.

Rob is saving to buy a new MP3 player. For every $13 he earns babysitting, he saves $9. On Saturday, Rob earned $78 babysitting.
stealth61 [152]

Answer:

54$

Step-by-step explanation:

We know that for each 13$ Rob earns babysitting, he saves 9$. Thus, we can separate the money he earns into groups of 13, and for each group of 13, we can add 9$ to his savings.

Assume that Rob has 78$ lying on a table. He grabs 13 of them, leaving 65, and puts 9$ to the side for savings. He does this 5 more times (as 65 divided by 13 is 5, so Rob would make 5 groups of 13 out of his 65$ that is left), meaning that he now has 5+1  (the original group) = 6 groups of 9. 9*6=54, so he saves 54$. Please let me know if you have any further questions!
