I am stuck on this practice problem. I would greatly appreciate any help! TIA!

A college student is interested in investigating the claim that students who graduate with a master's degree earn higher salaries, on average, than those who finish with a bachelor's degree. She surveys, at random, 42 recent graduates who completed their master's degrees, and finds that their mean salary is $31,300 per year. The standard deviation of annual salaries for the population of recent graduates who have master's degrees is known to be $900. She also surveys, at random, 31 recent graduates who completed their bachelor's degrees, and finds that their mean salary is $30,300 per year. The standard deviation of annual salaries for the population of recent graduates with only bachelor's degrees is known to be $2100. Test the claim at the 0.10 level of significance. Let recent graduates with a master's degree be Population 1 and let recent graduates with a bachelor's degree be Population 2. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho : HI = #2 Ha : HIO We reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance to support the student's claim that graduates with a master's degree earn higher salaries than those who finish with a bachelor's degree. O We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance to support the student's claim that graduates with a master's degree earn higher salaries than those who finish with a bachelor's degree. O We reject the null hypothesis and conclude that there is sufficient evidence at a 0. 10 level of significance to support the student's claim that graduates with a master's degree earn higher salaries than those who finish with a bachelor's degree. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance to support the student's claim O that graduates with a master's degree earn higher salaries than those who finish with a bachelor's degree
