On the C291Survey2020 worksheet of Assignment_10_Datasets_2022W2.xlsx Download Assignment_10_Datasets_2022W2.xlsxare selected variables from the 2020 online survey of C291 students. (Remember that our course name was C291 until this year.) Assume that these results represent a random sample of all Sauder undergraduate students in the past fewyears. The variables are as follows (coding is also provided as comments in the spreadsheet):

Incomplete records have been removed so you don't need to worry about missing data. There are 715 records in total.

You will test for differences between males and females with respect to the other variables. Use a 0.01 (i.e. 1%... not 5%!) level of significance for all tests.

Use all possible accuracy in your calculations; only for entry in Canvas should you round your answers to the number of decimal places instructed.
