These are the data that Dr. Pagels collected:
Blank 1 = row 1 total
Blank 2 = row 2 total
Blank 3 = column 1 total
Blank 4 = column 2 total
Blank 5 = grid total
Blank 6 = expected meadow vole/apple slices (round to nearest whole number)
Blank 7 = expected common vole/apple slices (round to nearest whole number)
Blank 8 = expected meadow vole/peanut butter-oatmeal (round to nearest whole number)
Blank 9 = expected common vole/peanut butter-oatmeal (round to nearest whole number)
Blank 10 = chi-square value (answer to 2 decimals)
Blank 11 = degrees of freedom
Blank 12 = chi-square critical value at 95% confidence (answer to 2 decimals)
Blank 13 = will you fail to reject the null hypothesis? (write your answer as either yes or no)
