A) 0.2433 B) 0.8994 * C) 0.1006 D) 0.7567 2.16501 22). 23) The business college computing center wants to determine the proportion of business students who have laptop computers. If the proportion exceeds 25%, then the lab will scale back a proposed enlargement of its facilities. Suppose 250 business students were randomly sampled and 75 have laptops. What assumptions are necessary for this test to be satisfied? A) The sample size n satisfies n2 30. B) The population has an approximately normal distribution. C) The sample proportion is close to 0.5. D) The sample size n satisfies both npo 2 15 and nqo 2 15. 23). 24) If a hypothesis test were conducted using a = 0.05, to which of the following p-values would cause the null hypothesis to be rejected. A) 0.055 B) 0.060

Expert Solution
Step 1

Given, n=Total Sample size =250

Sample proportion, p^=75250=0.3

H0:p=0.25H1:p>0.25, where p is the population proportion.
