The grades that students earned on their science test is normally distributed with an average score of 70 and a standard deviation of 8. What percentage of students scored between 54 and 78?
13.5 + 34 + 34 = 81.5

For the graph below, is Spearman's or Pearson's correlation coefficient appropriate? 
Spearman's because it its nonlinear and monotonic (as x goes up y goes up OR as x goes up y goes down)

The time it takes Billy to walk up a hill depends on the gradient (steepness) of the hill. The time it will take can be represented by the equation T=0.552G+6.36. Use the equation to predict how long it will take him to walk up a hill with G=4
8.568 (seconds)

ASB did a survey and found that 15% of students leave campus for lunch. Ms. Yee is going to randomly sample 20 students and wants to know the probability that 3 of them went of campus for lunch. Find the following:
bpd or bcd? x = ? n = ? p = ?
bpd x = 3 n = 20 p = 0.15

Phil uses Zyrtec allergy medicine. He recently heard that Allegra is a better allergy medicine. He is going to experiment to figure out if Allegra is better. Write the null and alternative hypothesis
H0: M1=M2
H1: M1<M2 (Zyrtec is worse than Allegra)

ASB did a survey and found that 15% of students leave campus for lunch. Ms. Yee is going to randomly sample 20 students and wants to know the probability that less than 5 of them went of campus for lunch. Find the following:
bpd or bcd? x = ? n = ? p = ?
bcd x = 4 (bc "less than 5") n = 20 p = 0.15

Ms. Brown investigated to see if height is related to how many pages a person reads per day. She got a p value of 0.12. Using a significance level of 10%, is height and pages read per day independent or dependent?
p (0.12) > significance level (0.10) so accept H0 (independent)
So, independent
