Q2. Use the contingency table to the right to calculate marginal frequencies and find the expected frequency for each cell in the contingency table. Assume that the variables are independent.
a)Calculate marginal frequencies and sample size.
b)Find the expected frequency for each cell in the contingency table.
Q3. Use the confidence interval to find the margin of error and sample mean. (0.424, 0.500)
