Answer 1

SOLUTION:

From given data,

Determine the critical value, , to test the claim about the population proportion P = 0.250 given n = 48 and = 0.231. Use = 0.01

Population proportion = P = 0.250

n = 48

= 0.231

= 0.01

Test hypothesis:

Null hypothesis : : P = 0.250

Alternative hypothesis : : P 0.250

Critical value :

= 0.01

/2 = 0.01/2 = 0.005

Z _/2 = Z_0.005 = 2.575

Answer : 4th option is correct
