In: Statistics and Probability
Consider a sample of 50 football games, where 33 of them were won by the home team. Use a 0.05 significance level to test the claim that the probability that the home team wins is greater than one-half. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0 : pequals 0.5Upper H 1 : pless than 0.5 B. Upper H 0 : pequals 0.5Upper H 1 : pgreater than 0.5 C. Upper H 0 : pgreater than 0.5Upper H 1 : pequals 0.5 D. Upper H 0 : pequals 0.5Upper H 1 : pnot equals 0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is nothing . (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is nothing . (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test.
The Hypotheses ate:
Ho: p=0.50
Ha : p>0.50
Rejection region:
Reject Ho if Z >Z 0.05 =1.645
The sample proportion is calculated as
Test statistic:
P-value:
The P-value is computed using Z table shown below as
P-value=0.012
Conclusion:
Since the P-value < 0.05 and Z > Z0.05 , hence we can reject the null hypothesis and conclude that there is sufficient evidence to support the claim.
