Soft Drink Consumption A researcher claims that the average yearly consumption of soft drinks per person is 52 gallons. In a sample of 46  randomly selected people, the mean of the yearly consumption was 53.8 gallons. The standard deviation of the population is 3.5 gallons. On the basis of the P -value, is the researcher's claim valid at α=0.01? State the hypotheses and identify the claim.   :H0 ▼(Choose one) :H1 ▼(Choose one) The hypothesis test is a ▼(Choose one) test. Compute the test value. Always round z  score values to at least two decimal places. z=
