Question:
Use the contingency table to the right to complete parts a through c below
a) Find the expected frequency for each cell
b) Compare the observed and expect frequencies for each cell
Choose the correct answer below
The totals for the observed and expected frequencies are the same.
The observed values are always greater than the expected values
The totals for the observed values are always greater than the totals for the expected values.
The expected values are always greater than the observed values.
c) Compute x2stat with alpha=0.01
Make sure to explain how you found the alpha, whether on excel or through formula
d) First let ?1 be the proportion of all events of interest in A, and let ?2 be the proportion of all events of interest in B. Determine the hypotheses
Then calculate the x 2 stat
Calculate the p value
Is the value significant at alpha 0.01?
