A random sample of 15 chemists from Washington state shows an average salary of $40118 with a standard deviation of $666. A random sample of 22 chemists from Florida state shows an average salary of $41749 with a standard deviation of $776. A chemist that has worked in both states believes that chemists in Washington make more than chemists in Florida. At a=0.01 is this chemist correct? Let Washington be sample 1 and Florida be sample 2. The correct hypotheses are: O Ho: µ1 < H2 HA: H1 > µ2(claim) Ο Η9: μι μ2 HA: H1 < µ2(claim) O Ho:µ1 = M2 HA:H1 # 42(claim) Since the level of significance is 0.01 the critical value is 2.445

O There is not enough evidence to reject the claim that chemists in Washington make more than chemists in Florida. O There is enough evidence to support the claim that chemists in Washington make more than chemists in Florida. O There is not enough evidence to support the claim that chemists in Washington make more than chemists in Florida.
