A random sample of 21 chemists from Washington state shows an average salary of $43206 with a standard deviation of $916. A random sample of 20 chemists from Florida state shows an average salary of $43138 with a standard deviation of $716. A chemist that has worked in both states believes that chemists in Washington make a different amount than chemists in Florida. At a=0.10 is this chemist correct? Let Washington be sample 1 and Florida be sample 2. The correct hypotheses are:

Question
The decision can be made to: O reject Ho do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that chemists in Washington make a different amount than chemists in Florida. O There is not enough evidence to reject the claim that chemists in Washington make a different amount than chemists in Florida. There is enough evidence to support the claim that chemists in Washington make a different amount than chemists in Florida. There is not enough evidence to support the claim that chemists in Washington make a different amount than chemists in Florida.

A chemist that has worked in both states believes that chemists in Washington make a different amount than chemists in Florida. At a=0.10 is this chemist correct? Let Washington be sample 1 and Florida be sample 2. The correct hypotheses are: O Ho:µ1 < µ2 HA: H1 > µ2(claim) O Ho: µ1 2 H2 HA: 41 < µ2(claim) O Ho: µ1 = µ2 HA: H1 + µ2(claim) Since the level of significance is 0.10 the critical value is 1.686 and -1.686 The test statistic is: (round to 3 places) The p-value is: (round to 3 places)
