A baseball team claims that the mean length of its games is 1.6 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ=1.6." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.6." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.6." D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is…

st 3 4 25 26 27 28 on 29 K Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. O A. Ho: P₁ = P2 H₁: P₁ P2 OB. Ho: P₁ P2 H₁: P₁ P2 OC.…

In 1992 a national vital statistics report indicated that about 2.3% of all births produced twins. Is the rate of twin births the same among very young mothers? Data from a large city hospital found only 7 sets of twins were born to 455 teenage girls. Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. Are the assumptions and the conditions to perform a one-proportion z-test met? ... No Yes State the null and alternative hypotheses. Choose the correct answer below. A. Ho: p=0.023 HA: P >0.023 B. Ho: p=0.023 HA: P = 0.023 C. Ho: p=0.023 HA: P<0.023 D. The assumptions and conditions are not met, so the test cannot proceed. Determine the z-test statistic.
