Some individuals are carriers of the bacterium Streptococcus pyogenes. Investigators examined 1398 schoolchildren to determine if they were carriers or not, and noted the size of their tonsils. Here are the results: Tonsil Size normal large very large Total Carrier 19 29 24 72 Non-carrier 497 560 269 1326 Total 516 589 293 1398 a. [3 points] State the hypotheses that should be used to test if the relationship between carrier status and tonsil size is statistically significant. b. [2 points] The appropriate hypothesis test was conducted and resulted in a p-value of 0.0194. Should the null hypothesis be rejected at the 5% level of significance? Explain why or why not (you may draw a graph to explain). c. [3 points] What is the probability that an individual has normal tonsils? You may leave your answer as a fraction, or report to 3 decimal places. d. [4 points] Given an individual has tonsils of normal size, what is the probability that the individual is a carrier? You may leave your answer as a fraction, or report to 3 decimal places. e. [4 points] Use a 95% level of confidence to estimate the difference in proportion of individuals with normal tonsils between carriers and non-carriers.
