Write the word or phrase that best completes each statement or answers the question.
Use the traditional method to test the given hypothesis. Assume that the samples are independent and that they have been randomly selected
- $\mathrm { x } _ { 1 } = 15 , \mathrm { n } _ { 1 } = 50 \text { and } \mathrm { x } _ { 2 } = 23 , \mathrm { n } _ { 2 }$ = 60; Construct a 90% confidence interval for the difference between population proportions p1 - p2.
