d.) 202

Answer 1

217

Explanation:

Answer 2

C.) 217 (I promise, I just did this with a teacher!)

Explanation:

Think about it, you're looking for the top 4% so the score has to be better than about 96% of everyone else who tried out for the team.

1.74 matches up with 95.91 on the z score table.

Following the equation: z = raw score - mean over over standard deviation

z is 1.74

so the equation should look something like 1.74 = x - 200/ 10

Solve for x and get 217.4 which can be rounded to 217 which is your answer.
