After conducting a study to determine the gender of characters which appear most on cereal boxes, the manager of a large supermarket believes that of the 1386 character whose gender was determined, 996 (72%) were male characters and 390 (28%) were female characters. Does the survey support the manager’s belief about the frequency of male characters appear more often than female characters on cereal boxes? Use a significance level of 0.05. Restate the question as a null and alternative hypothesis. H0: H1: State the level of significance. Level of significance = Determine the degrees of freedom. Degrees of freedom = Determine the test statistic by filling in the table below: Observed freq (O) Expected freq (E) (O – E) (O – E)2 (O – E)2/E (O – E)2/E Male Female Test statistic = Determine the Critical value. State your conclusion.
