POSSIBLE POINTS: 5 The parent association at a local high school believes that the amount of time spent on homework by students at the school, on average, is more than the school's policy of an average of 30 minutes of homework per class. To test this claim, the administrators selected a random sample of 50 students, calculated the amount of time each student spent on homework per class. The mean number of minutes spent on homework, per class, for the students in the sample was I = 34.7 minutes and the standard deviation was s = 10.4 minutes. The administrators performed a significance test and obtained a P-value of 0.0012. What conclusion would you make for the given significance test levels? O For only a = 0.01 we would reject Ho. There is convincing evidence the mean time spent on homework by students at the school is more than 30 minutes per class at a = 0.01, but not at a = 0.05 For both a = 0.01 and or = 0.05, we would fail to reject Ho. There is not convincing evidence the mean time spent on homework by students at the school is more than 30 minutes per class at either significance level. O For only a = 0.05 we would reject Ho. There is convincing evidence the mean time spent on homework by students at the school is more than 30 minutes per class at a = 0.05, but not at a = 0.01 For both a = 0.01 and a = 0.05, we would reject Ho. There is convincing evidence the mean time spent on homework by students at the school is more than 30 minutes per class at both significance levels
