Two Sample Hypothesis Test

Show all five steps in your analysis. To get full credit you must label the CV (critical value) and TV (Test Value) in your drawing. Use the p-value for this test.

A teacher claims 9 year old girls are taller than 9 year old boys. Test this claim at an alpha level of .05. A researcher randomly selected a sample of 60 boys and another sample of 50 girls. The statistics from these two samples are shown below: Boys: n = 60, mean = 123.5 cm, and standard deviation = 9.9 cm Girls: n = 50, mean = 126.2, and standard deviation = 10.9 cm

What type of test are you going to perform? ______________________________
