It is telling me the alternative hypothesis is incorrect as well as the p-value. So just needing help with b & e

Past records suggest that the mean annual income, µ, of teachers in state of Utah is greater than or equal to the mean annual income, µ,, of teachers in Oregon. In a current study, a random sample of 25 teachers from Utah and an independent random sample of 25 teachers from Oregon have been asked to report their mean annual income.The data obtained are as follows. Annual income in dollars 41264, 29116, 23631, 46394, 28063, 31348, 37830, 41456, 39553, 39619, 32624, 21944, 35824, 36126, 33402, 30834, Utah 46644, 37004, 38100, 40820, 29763, 32664, 38361, 35726, 23918 35762, 37557, 42852, 38904, 38141, 37413, 37216, 39112, 47116, 25804, 40956, 40207, 31363, 29097, 46144, 43432, Oregon 41236, 39786, 46860, 41954, 49300, 39676, 45148, 43630, 39248 Send data to calculator Send data to Excel The population standard deviation for mean annual income of teachers in Utah and in Oregon are estimated as 6400 and 6500, respectively. It is also known that both populations are approximately normally distributed. At the 0.01 level of significance, is there sufficient evidence to reject the claim that the mean annual income of teachers in state of Utah is greater than or equal to the mean annual income of teachers in Oregon? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
