A random sample of 25 chemists from Washington state shows an average salary deviation of $942. A random sample of 18 chemists from Florida state shows an with a standard deviation of $561. A chemist that has worked in both states beli Washington make less than chemists in Florida. At a=0.05 is this chemist correct 1 and Florida be sample 2. The correct hypotheses are: O Ho: 1 ≤2 HA: μι > μ2(claim) Ο Ho: μι 2 με HA: 12(claim) O Ho: ₁ = ₂ HA: 12(claim) Since the level of significance is 0.05 the critical value is -1.684

Question
A random sample of 25 chemists from Washington state shows an average salary of $48123 with a standard deviation of $942. A random sample of 18 chemists from Florida state shows an average salary of $49603 with a standard deviation of $561. A chemist that has worked in both states believes that chemists in Washington make less than chemists in Florida. At a=0.05 is this chemist correct? Let Washington be sample 1 and Florida be sample 2. The correct hypotheses are: Ο Η: μι < με HA: μι > μ2(claim) © Ho: μι 2 μ2 HA: M1 M₂(claim) O Ho: ₁ = ₂ HA: 12(claim) Since the level of significance is 0.05 the critical value is -1.684 (round to 3 places) The test statistic is: The p-value is: (round to 3 places)
