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.)

You have a sample of 48 randomly selected Vancouverites. On average (the sample mean), the people in your sample spent 425 hours eating food in 2020. The least time a person in the sample spent eating food in 2020 is 367 hours and the most time a person in the sample spent eating food in 2020 is 484 hours. What would be your best guess about the population standard deviation of the time a Vancouverite spent eating food in 2020? Give the number and explain (including assumptions you make about the population distribution).

Type if A if you should accept the study as having a mean not to different from the population mean. Type R if you should reject the study as having a too different mean from the population mean. A researcher wants to determine whether the mean height of 31, 18 year old Filipino teens is significantly different from the population average of 5.2 ft. The mean and the standard deviation of the scores of the researcher's study is 5.4 ft and 7; respectively. Assume a 99% confidence level.
