Perform chi-squared test with Yates'

A question is this type if and only if it requires carrying out a complete chi-squared test using Yates' correction on a 2×2 contingency table, including calculating the test statistic, comparing to critical value, and reaching a conclusion.

  1. When should Yates' correction be applied when carrying out a \(\chi ^ { 2 }\) test? Two vaccines against typhoid fever, \(A\) and \(B\), were tested on a total of 700 people in Nepal during a particular year. The vaccines were allocated randomly and whether or not typhoid had developed was noted during the following year. The results are shown in the table.
    \multirow{2}{*}{}Vaccines
    \cline { 2 - 3 }\(A\)\(B\)

  2. Carry out a suitable \(\chi ^ { 2 }\) test at the \(1 \%\) significance level to determine whether the outcome depends on the vaccine used. Comment on the result.

How Yates' correction is applied

A question is this type if and only if it asks for the method or procedure of applying Yates' correction (subtracting 0.5 from |O-E| before squaring) and/or whether it increases or decreases the chi-squared value.

Hypothesis test given corrected statistic

A question is this type if and only if the Yates-corrected chi-squared value is already provided and the task is to perform the hypothesis test (compare to critical value and conclude) at a specified significance level.
