Construct the Indicated Confidence Interval for the Difference Between Population $\mathrm { p } _ { 1 } - \mathrm { p } _ { 2 }$

Multiple Choice

Construct the indicated confidence interval for the difference between population proportions p1 - p2. Assume that the samples are independent and that they have been randomly selected.
-x1=65,n1=90 and x2=79,n2=116,construct a 98% confidence interival for the difference berween
population proportions $\mathrm { p } _ { 1 } - \mathrm { p } _ { 2 }$ .

A) $- 0.084 < \mathrm { p } _ { 1 } - \mathrm { p } _ { 2 } < 0.848$
B) $- 0.108 < \mathrm { p } _ { 1 } - \mathrm { p } _ { 2 } < 0.190$
C) $0.596 < \mathrm { p } _ { 1 } - \mathrm { p } _ { 2 } < 0.848$
D) $0.572 < p _ { 1 } - p _ { 2 } < 0.872$
