Transcribed Image Text:9.
A particular strand of DNA was classified into one of three genotypes: E4/E4*, E4/E4, and E4/E4. In addition to a sample of 2,098 young adults (20-24 years), two other age groups were studied: a sample of 2,184 middle-aged adults (40-44 years) and a sample of 2,279 elderly adults (60-64 years). The accompanying table gives a breakdown of the number of adults with the three genotypes in each age category for the total sample of 6,561 adults.
Researchers concluded that "there were no significant genotype differences across the three age groups" using a = 0.05. Are they correct?
