Question

A researcher wished to compare the average amount of time spent in extracurricular activities by high school students in a suburban school district with that in a school district of a large city. The researcher obtained a simple random sample of 60 high school students in a large suburban school district and found the mean time spent in extracurricular activities per week to be 6 hours with a standard deviation of 3 hours. The researcher also obtained an independent simple random sample of 40 high school students in a large city school district and found the mean time spent in extracurricular activities per week to be 4 hours with a standard deviation of 2 hours. Let μ 1 and μ 2 represent the mean amount of time spent in extracurricular activities per week by the populations of all high school students in the suburban and city school districts, respectively. Assume two sample t procedures are safe to use. Reference: Ref 7-14 Suppose the researcher had wished to test the hypotheses H o: 1-2 versus H a: μ μ 2. What can we say about the value of the P-value? P-value<0.01 0.01 <P-value0.05 0.05<P-value<0.10 P-value> 0.10
