Researchers conduct a study to determine that having a gene disruption may be related to an increased risk of developing dyslexia. The two-way table indicates whether those having the gene disruption have a different proportion of dyslexia versus no dyslexia. Dyslexia No Dyslexia (control) Total Gene disruption 18 15 33 No gene disruption 99 185 284 Total 117 200 317 a. Use Calculator to perfom a 95% confidence interval estimate for the difference proportion in dyslexia vs no dyslexia of the GENE Disruption group. Use 3 decimal places. INTERPRET your findings in a complete sentence. b. Perform a hypothesis test to determine whether there is a difference in proportion of those with the gene disruption who have dyslexia versus those with no dyslexia 1. State the null and alternative hypotheses. Using correct notation. 2. Use your calculator to perform the appropriate test. Identify the calaulator menu function you use, and identify the resulting test statistic and p-value. Use 3 decimal places 3. At a=.05 signifieance level, what is your conelusion for your test? Give any comments in a compete sentence.
