For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
<span>19.47 is 66% of 29.5.
hope this helps! :)</span>
1) 3 times 15 is 45
6) because in order for it to even have a slope it has to be constant through out the whole thing.
