Congenital sensorineural deafness is the most common form of deafness in dogs and is often associated with congenital pigmentation deciencies. A study of hearing impairment in dogs examined more than 5000 Dalmatians for both hearing impairment and iris color. Dogs with either one or both of their irises blue (a trait attributable to low iris pigmentation) were labeled \"blue-eyed.\" Here is a contingency table with the results Brown - eyed Blue - eyed Deaf 324 102 Unilateral impaired 988 179 Bilateral hearing 3467 273 1. Describe the differences between the distributions of hearing impairments among brown-eyed and blue-eyed dogs with percents, with a bar graph, and in words. 2. Find the expected counts and verify that they satisfy the requirement for use of chi-square. 3. Conduct a hypothesis to test whether there is a relationship between hearing impairment and iris color. State the null and alternative hypotheses, test statistic, degrees of freedom, and p-value. 4. How do the observed and expected counts differ? Relate this to your conclusions in
