P-Value Find the P-value in a test of the claim that the mean annual income of a nurse is greater than $60,000 (based on data from the Bureau of Labor Statistics) given that the test statistic is t = 2.462 for a sample of 30 nurses.

You wish to determine which of two brands of TVs is more expensive. You conduct the following sample, which suggests that Orion TVs are more expensive: Orion: ā = $318, sª = 12.6, п — 30 Luna: ā = $313, 8z = 15.1, n = 25 Define your variable: O Let p be the proprotion Orion TVs in the sample that cost more than Luna TVs. OLet u be the mean price of TVs, in dollars Let mu the mean price of Orion TVs, in dollars. Let u be the mean price of sampled TVs, in dollars. Write your hypotheses: Be sure to chose Group 1 to have the larger sample mean. Но: Opi – P2 = 0 O pi – P2 = 318 – 313 Ο μ-μ 5 µi - µ2 = 0 HA: Hi – µ2 > 0 O ui – u2 < 0 µi – µ2 = 5 Opi - - P2 = 318 – 313
