A December 2017 Gallup Poll reported that 43% of Americans use the internet for an hour or more each day. You suspect that a greater proportion of students at your school use the internet that much. You take a random sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school has more than 600 students. You will test the hypotheses H0 : p = 0.43; Ha : p > 0.43, where p = the true proportion of students at your school who use the internet for an hour or more each day using = 0.01. What is the P-value and appropriate decision for this test? a. P-value = 0.004; reject H0 b. P-value = 0.004; fail to reject H0 c. P-value = 0.0103; reject H0 d. P-value = 0.0103; fail to reject H0 e. no conclusion can be drawn, because the conditions have not been met.

You suspect that a greater proportion of students at your school use the internet that much. You take a random
sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school
has more than 600 students. You will test the hypotheses H0 : p = 0.43; Ha : p > 0.43, where p = the true
proportion of students at your school who use the internet for an hour or more each day using = 0.01. What is the
P-value and appropriate decision for this test?
a. P-value = 0.004; reject H0
b. P-value = 0.004; fail to reject H0
c. P-value = 0.0103; reject H0
d. P-value = 0.0103; fail to reject H0
e. no conclusion can be drawn, because the conditions have not been met.
