A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in Texas and Indiana. Due to recent trends in the childcare industry,
the firm suspects that the mean annual income of childcare workers in Texas is less than the mean annual income of childcare workers in Indiana. To see if this
is true, the firm selected a random sample of 10 childcare workers from Texas and an independent random sample of 10 childcare workers from Indiana and
asked them to report their mean annual income. The data obtained were as follows.
Annual income in dollars
Texas 35102, 40287, 32854, 29080, 36394, 22024, 22493, 31602, 27434, 40040
Indiana 38446, 33018, 38027, 43504, 37962, 33838, 35730, 36793, 37714, 25715

The population standard deviation for the annual incomes of childcare workers in Texas and in Indiana are estimated as 6200 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 support the claim that the
mean annual income, H₁, of childcare workers in Texas is less than the mean annual income, μ₂, of childcare workers in Indiana? Perform a one-tailed test. Then
complete the parts below.
