Records indicate 96 boys and 127 girls born in the past month. Follow and list the eight steps for hypothesis testing to determine if there is a statistically significant difference. 3. For the observed frequencies in the table below, conduct a chi-square test to determine if there is a relationship between the variables. Follow and list all 8 steps for hypothesis testing.
