A grocery store says their mangoes are fresher than most. A typical grocery store has roughly 10% go bad before they sell. A random sample of 135 mangoes from the store showed that 13 of the mangoes were rotten. Assume we have a significance level of 0.05. 1. null hypothesis____________ the alternative hypothesis is__________ 2. Our z-test statistic is 3. Our p-value is 4. evidence supporting the alternative?
you compute a two-sample z statistic and it comes out to equal 1.6. What is the p-value if you are doing a two-tailed test? Enter a value between 0 and 100 corresponding to the percentage, e.g. if your p-value equals 2.4%, enter 2.4. Any correctly rounded version will receive full credit.
Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error. True False
Consider a sample of 54 football games, where 30 of them were won by the home team. Use a 0.10 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. OA. Ho: p=0.5 H₁: p0.5 OC. Ho: p>0.5 H₁: p=0.5 OD. Ho: p=0.5 H₁: p 0.5 Identify the test statistic for this hypothesis test.
