A recent report claimed that 13% of students typically walk to school. DeAnna thinks that the proportion is higher than 0.13 at her large elementary school. She surveys a random sample of 100 students and finds that 17 typically walk to school. DeAnna would like to carry out a test at the a = 0.05 significance level of Но : р —D 0.13 На : р> 0.13 where p = the true proportion of all students at her elementary school who typically walk to school. What conclusion would you make? Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We do not have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we reject Ho. We do not have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we reject Ho. We have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13.

Question
Transcribed Image Text:A recent report claimed that 13% of students typically walk to school. DeAnna thinks that the proportion is higher than 0.13 at
her large elementary school. She surveys a random sample of 100 students and finds that 17 typically walk to school. DeAnna
would like to carry out a test at the a =
0.05 significance level of
Но : р %3D 0.13
На : р> 0.13
where
= the true proportion of all students at her elementary school who typically walk to school.
What conclusion would you make?
Because the P-value of 0.1170 > a =
0.05, we fail to reject Ho. We have convincing evidence that the true proportion
0•
of all students at this elementary school who typically walk to school is greater than 0.13.
Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We do not have convincing evidence that the true
proportion of all students at this elementary school who typically walk to school is greater than 0.13.
Because the P-value of 0.1170 > a =
0.05, we reject Họ. We do not have convincing evidence that the true proportion
of all students at this elementary school who typically walk to school is greater than 0.13.
Because the P-value of 0.1170 > a =
0.05, we reject Ho. We have convincing evidence that the true proportion of all
students at this elementary school who typically walk to school is greater than 0.13.
