Your friend tells you that the proportion of active Major League Baseball players whohave a batting average greater than .300 is greater than 0.53, a claim you would liketo test. The hypotheses for this test are Null Hypothesis: p < 0.53, AlternativeHypothesis: p > 0.53. If you randomly sample 26 players and determine that 18 ofthem have a batting average higher than .300, what is the test statistic and p-value?1) Test Statistic: -1.658, P-Value: 0.049O 2) Test Statistic: -1.658, P-Value: 0.9513) Test Statistic: 1.658, P-Value: 0.0494) Test Statistic: 1.658, P-Value: 0.951O 5) Test Statistic: 1.658, P-Value: 0.098

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.
A news article that you read stated that 59% of voters prefer the Democratic candidate. You think that the actual percent is different. 120 of the 236 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?Select an answerv (please enter a decimal) H.:?Select an answerv (Please enter a decimal) c. The test statistic ?V = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?va f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly different 59% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 59%.
