A researcher claims that the average yearly consumption of soft drinks per person is 52 gallons. In a sample of 59 randomly selected people, the mean of the yearly consumption was 53.2 gallons. The standard deviation of the population is 3-5 gallons. Is the researcher's claim valid at a=0.10? a) State the hypotheses and identify the claim with the correct hypothesis. 01. Ho:p=53.2 claim H1:2#53.2 Not claim 02. Ho::+52 Not claim H1:=52 claim 03. Ho:u=52 claim H1:+52 Not claim b) Find the critical value (s). 01. CV=+1.96 21 2.CV=+165

Ho:u=52 claim Hp+52 Not claim b) Find the critical value (s). 01. CV=+1.96 2. CV=+1.65 3. CV= -2.58 c) Compute the test value: 01. Z= -0.85 2. z=2.63 03. z= 2.21 d) Make the decision. 01. Reject the null hypothesis. 2. Do not reject the null hypothesis.

e) Summarize the results. 01. There is enough evidence to support the claim. o 2.There is not enough evidence to support the claim.
