Suppose the true proportion of high school students who walk to school in New York City is 0.82. If many random samples of 400 high school students are taken, by how much would their sample proportions typically vary from the true proportion? a. 0
b. 0.001
c. 0.019
d. 0.148
e. 7.684

i think it will be C

Step-by-step explanation:

with the variability formula = squareroot p(1-p)/n which gives you 0.0192

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
