TDaP is a booster shot that prevents Diphtheria, Tetanus, and Pertussis in adults and adolescents. It should be administered every 8 years in order for it to remain effective. A random sample of 500 people living in a town that experienced a pertussis outbreak this year were divided into two groups.

Group 1 was made up of 132 individuals who had not had the TDaP booster in the past 8 years, and
Group 2 consisted of 368 individuals who had.
In Group 1, 15 individuals caught pertussis during the outbreak, and in Group 2, 11 individuals caught pertussis.

Is there evidence to suggest that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higherthan those that were?
Test at the 0.05 level of significance.

Enter the test statistic - round to 4 decimal places.
Enter the P-Value - round to 4 decimal places.

Is there evidence to suggest the proportion of those who caught pertussis is higher for those who were not up to date on their booster (Y/N)?
