survey was conducted that asked AHC (Population 1) students and Cuesta students if they drive to school. he calculator output from a hypothesis test looks like this: -PropZTest E = 1.8 = 0.072 = 0.72 2 = 0.62 = = 0.68 . What was the claim? O AHC and Cuesta students are equally likely to drive to school O AHC students are more likely than Cuesta students to drive to school O On average, the same number of AHC students and Cuésta students drive to school OA higher number of AHC than Cuesta students drive to school . Was the test statistically significant at a = 0.05? O No, since 0.68 > 0.05 O No, since 0.072 > 0.05 O Yes, since 0.072 < 0.05 O No, since 1.8 > 0.05 E.

Answer b through d
A survey was conducted that asked AHC (Population 1) students and Cuesta students if they drive to school.
The calculator output from a hypothesis test looks like this:
2-PropZTest
Pi + P2
Z = 1.8
p= 0.072
Pi = 0.72
P2 = 0.62
p = 0.68
a. What was the claim?
O AHC and Cuesta students are equally likely to drive to school
O AHC students are more likely than Cuesta students to drive to school
O On average, the same number of AHC students and Cuésta students drive to school
OA higher number of AHC than Cuesta students drive to school
b. Was the test statistically significant at a = 0.05?
O No, since 0.68 > 0.05
O No, since 0.072 > 0.05
O Yes, since 0.072 < 0.05
ONo, since 1.8 > 0.05
c. What percentage of the AHC students drive to school?
d. What is the combined percentage of AHC and Cuesta students that drive to school?
