If you want to estimate to the tens, the answer is 680
If you want to estimate to the hundreds, the answer is 700
If you want to estimate to the thousands then the answer would be not an answer
The real answer without estimating is 681
Answer:
The experimental probability is 4%
Step-by-step explanation:
<span>Stem-and-leaf plots are used for showing the frequency of which certain classes of values occur. use a stem-and-leaf plot and let the numbers themselves to show pretty much the same information. In short, they are meant to show frequencies of which numbers or values occur. Not for colors or objects.
Yes, a frequency table is a perfect way to solve the problem! These are meant to help you find the number of something that occurs, and is a simple and clean way to show your word.</span>
Answer
a. True
Step-by-step explanation:
Based on this survey we estimate that about of the college students smokes. And a confidence interval is . So we know that our estimative for the smoking rate is in the confidence interval with certainty. We also know the estimative for the smoking rate in the general population is . So we can write the two possible hypothesis:
Smoking rate is equal to .
Smoking rate is not equal to .
We will reject the null hypothesis if the estimate doesn't fall into the confidence interval for the college students smoking rate.
Since this condition holds we reject the null hypothesis. So with certainty we say that the smoking rate for the general population is different than the smoking rate for the college students.
Your answer is h (20’mm) x^c’’
