An official of a large national union claims that the fraction of women in the union is not significantly different from one-half.Using the critical value approach and the sample information reported below, carry out a test of this statement.Let α = .05. 
Critical Value
A threshold in hypothesis testing that defines the boundary or cutoff point at which the test statistic is considered significant.
Null Hypothesis
A hypothesis that suggests there is no statistical significance between the two specified populations or sets of data.
