12.Does the extent to which college graduates want to changethe world differ by type of major? To find out, Pedro asks 33graduating seniors (11 humanities majors, 11 social science majors,11 natural science majors) to rate their desire to change the worldon a 7-point scale.Which statistical test should Pedro use to analyze the data?Be specific. Why should this particular test be used?What are the degrees of freedom for the comparisondistribution?What is the critical value of the test statistic (a= .05)?Pedro runs the test and finds that F = 2.93. Whatshould Pedro conclude about whether college graduates' desire toobtchange the world differs by type of major?

1.) Data can be misrepresented through graphs. Try to find an example of a misleading graph in the real world. Check magazines, papers, internet, etc. Then upload the graph and say what can be misleading. 2.)

The questions below are based on a dataset containing the characteristics of 5,407households. In particular, we will use the following variables:- size: home size, measured in square feet.- hhinc: annual household net income, measured in euros.- owner: dummy variable equal to 1 if the living space is owned, and 0 if the livingspace is rented.- hhsize1: dummy variable equal to 1 if the number of household’s members is 1 or2, and 0 otherwise.- hhsize2: dummy variable equal to 1 if the number of household’s members is 3 or4, and 0 otherwise.- hhsize3: dummy variable equal to 1 if the number of household’s members is 5 orabove 5, and 0 otherwise.- edu: education level of household’s members. We conduct a simple regression of size on hhinc, now using robust standard errors.The regression output is reported in Table 2. Why are the estimated coefficients inTable 2 equal to the estimated coefficients in Table 1? Do the conclusions on thestatistical significance at 5% of the coefficient of…
