moet de volgende opdrachten voor morgen 3 uur afhebben alleen snap er tot nu toe vrij weinig van. Iemand die er wel iets van snapt en zin heeft in wat opdrachten

Mijn dank zou groot zijn

Question 9: In a five years old study it was concluded that:
1) If a household receives €1000 (so, 1 unit) more annual income, then the annual expenditures on food + housing will on average increase by €600 (so, 0.6 units).
2) If a household receives €1000 more annual income, then the annual expenditures on clothing + recreation will on average increase by €160.
Use regression analysis to investigate whether nowadays:
- the average increase of TOTEXP1 in case of an increase of €1000 of the annual household income differs from €600;
- the average increase of TOTEXP2 in case of an increase of €1000 of the annual household income is more than €160.
Use 95%-confidence intervals to find answers to these research questions. Present your research results in a table containing the two relevant 95%-confidence intervals, the two alternative hypotheses, and the two statistical conclusions.
Question 10: Interpret briefly the results of the previous questions. What do the tables, graphs, statistics and tests tell you? Be concise, and avoid personal opinions!
