Question

Question 27 2.5 pts In the test of hypothesis Ho := 100vs H, :p # 100. A sample of size 100 yields the standard test statistic z = 2.50. The P-value for this test is closest to 01. 1.9876 0 0.0124 0.9938 0.0062

Answer 1

Solution :-

Given :-

Hypothesis :

Ho : u = 100

H1 : u $\neq$ 100

The Given test is a two tailed test.

z = 2.50 ( Given )

By using Standard normal table,

P ( z > 2.50 ) = 1 - P ( z < 2.50 )

P ( z > 2.50 ) = 1 - 0.9938

P ( z > 2.50 ) = 0.0062

Since, it is two tailed test

P -Value = 2 * 0.0062

P -value = 0.0124
