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, and tested the hypotheses listed here: H: μ- 30 Ha : μ> 30 %3| Where = the mean number of minutes spent on homework, per class, for all students in the school. The mean number of minutes spent on homework, per class, for the students in the sample was = 34. 7 minutes and the standard deviation ST = 10. 4 was 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?
