A study from 2005 claims that high school students are active for 60 minutes a day on average. A researcher believes this has decreased over time. He randomly selects a group of high school students nationwide and determines the group’s average amount of activity to be 50 minutes. If the p-value for this new study is 0.03 and the researcher is using an alpha of 0.05, what should the researcher conclude?
A There is evidence at the 0.05 level of significance that high school students on average are active for less than 60 minutes a day
B There is evidence at the 0.05 level of significance that high school students on average are active for more than 60 minutes a day
C There is evidence at the 0.05 level of significance that high school students on average are active for approximately 60 minutes a day
D There is not enough information provided to reject or fail to reject the null hypothesis.
