Question

Question 16 1 pts The business college computing center wants to determine the proportion of business students who have personal computers (PC's) at home. If the proportion differs from 25%, then the lab will modify a proposed enlargement of its facilities. Suppose a hypothesis test is conducted and the test statistic is 2.4. Find the P-value for a two-tailed test of hypothesis. 0.0164 0.0082 0.4836 0.4918

Answer 1

Here we have to test that

Null hyothesis: $H_0:p=0.25$

Alternative hypothesis: $H_1:p\neq 0.25$

Test is two tailed test.

Test statistic = 2.4

P value = 2 * P(z > 2.4)

= 2 * (1 - P(z < 2.4))

= 2 * ( 1 - 0.9918) (From statistical table of z values)

= 2 * 0.0082

= 0.0164

P value = 0.0164
