i'm pretty sure it's C

-1 times -1 becomes positive, and then times -1 again, it's negative, and times it again, it's positive, and <em>THEN</em> one more time (lol) it's -1.

Surveys conducted in American high schools concluded that 90% of the students in a sample of 400 students had more than one acti
kenny6666 [7]
The sample proportion has an approximately normal distribution, with the mean being the population mean and the standard deviation (i.e. the standard error of the sampling proportion) equal to 

SE = sqrt(p*q/n) where p is the population proportion q is 1-p, and n is the sample size. 

<span>(Typically, for a confkdence interval, the sample proportion and its complement are substituted for p and q.) </span>

The margin of error will be Zc*SE, where Zc is the critical value of Z for the level of confidence required. The confidence interval, then, will be the sample proportion, plus or minus the margin of error. 

For a 90% confidence interval, Zc is 1.645. 

<span>So the margin of error is 1.645 * sqrt(.9*.1/400), roughly .025. So your confidence interval would be around [.875, .925] 


The best and most correct answer among the choices provided by your question is the second choice or letter C which is 3%.

Answer:

3 are mushed

Step-by-step explanation:

You have 12 tomatoes

All but 9 get mushed

Total tomatoes = mushed + non mushed

12 = mushed +9

Subtract 9 from each side

12-9 = mushed+9-9

12-9 = mushed

3 = mushed
