A researcher wishes to test the claim that the average cost of tuition and fees at a four year public college is greater than $5700. She selects a random sample of 36 four-year public colleges and finds the mean to be $5950. The population standard deviation is $659. Is there evidence to support the claim at 0.05? STEP 1. State the null and alternate hypothesis. CHOOSE THE LETTER THAT CORRESPONDS TO THE CORRECT ANSWER. A C D H = 5700 H = 5700 H = 5700 µ = 5700 H = 5700 u = 5950 H #5950 H> 5700 µ< 5700 U 5700 STEP 2. The critical value (s) is/are: Z1 = 1.64 Z2 = N/A (IF THERE IS ONLY ONE CRITICAL VALUE ENTER IT IN THE LEFT BOX AND ENTER N/A IN THE RIGHT BOX.)
