2. Compare the differentSocioeconomic Levels (ses_level)of the students in the Psych_Data.xlsx dataset to determine if there is astatistically significant differencein the meanAnxiety Scores (anx_score)between the different SES levels. Be sure to state the type of test, state the Ho and Ha, include all relevant Excel results and plots, and write final conclusions for the full results of the test in context. Be sure that your final conclusions are written in common terms for an average person to understand.

(a) What type of hypothesis test will you run?

(b) State the Ho and Ha.

(c) Include descriptive statistics (mean, standard deviation, sample size)ANDan appropriate graphical display that allows you to visually compare theAnxiety Scoresfor the three SES groups. Copy/paste the numerical summaries and graph hereANDdescribe the similarities and differences in theAnxiety Scoresof the three groups (address central tendency and variation of the three groups in your discussion).

(d) Give the test statistic, p-value, and decision from your test results (include Excel output). Would a post-hoc be necessary - why or why not?

(e) Write a full conclusion (in context) for the results on this test in a way that can be understood by a non-statistical person. This answer will be at least 100 words or more.
