(A) 10/64 (1.960)V(10/64)(1-10/64)/64 (B) 8/60± (1.645)V(8/60)(1-8/60)/60 (C) 8/60 t (1.960)(8/60)(1 - 8/60)/60 (D) 10/64± (1.645) V (10/64)(1-10764)/ 64
Answers
At 95% confidence interval the critical value is z0.025 = 1.96
= 8/60
The 95% confidence interval for population proportion p is
+/- z0.025 *
= 8/60 +/- 1.96 *
Option - C is correct.
