researcher suspects that color blindness is inherited by a sex-linked gene. This possibility is examined by looking for a relationship between gender and color vision. A sample of 1000 people is tested for color blindness, and then they are classified according to their sex and color vision status (normal, red-green blind and other color blindness). Is color blindness related to gender? The data are as follows: Observed Frequencies of Color Vision Status According to Sex Normal Color Vision Red-Green Color Blindness Other Color Blindness Totals Male 320 70 10 400 Female 580 10 10 600 Totals 900 80 20 State the hypotheses. Determine the value for df, and locate the critical region. Compute the fe values and then chi-square. Make a decision regarding Ho.
