A scientist has read that the mean birth weight of babies born at full term is 7.4 pounds. The scentist has good reason to believe that the mean birth weight ofbabies born at full term, µ, is greater than this value and plans to perform a statistical test. She selects a random sample of birth weights of babies born at fullterm and finds the mean of the sample to be 7.8 pounds and the standard deviation to be 1.6 pounds.Based on this information, complete the parts below.(a) what are the null hypothesis H, and the alternative hypothesis H, that should be used for the test?Ho :0O

Test is that mean birth weight of babies born at full form is greater than 7.4 pounds. The type I…

The FDA regulates that fish that is consumed is allowed to contain 1 mg/kg of mercury. In Alaska, bass fish were collected in 36 different lakes to measure the amount of mercury in the fish. Do the data provide enough evidence to show that the fish in Alaska lakes has more mercury than the allowable amount? Below, set up the Null Hypothesis Ho and the Alternative Hypothesis HA. Ho: H (? HẠ: H (?
Below is the full question for the last question Fail to reject / reject the null hypothesis. There is / is not enough evidence to Support / reject the claim
Suppose the null hypothesis, Ho, is: the mean age of the horses on a ranch is 6 years. What is the Type lI error in this scenario? Select the correct answer below: O O O O You think the mean age of the horses on a ranch is 6 years when, in fact, it is. You think the mean age of the horses on a ranch is 6 years when, in fact, it is not. You think the mean age of the horses is not 6 years when, in fact, it is. You think the mean age of the horses is not 6 years when, in fact, it is not.
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.…

The average final exam score for the statistics course is 78%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 90, 84, 93, 77, 95, 79, 82, 70, 85, 70, 83, 100, 90 What can be concluded at the the a = 0.05 level of significance level of significance?
A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are H0:p = 0.4 and Ha: p < 0.4. The test statistic and p-value for the test are z = -3.01 and p-value = 0.0013. For asignificance level of a= 0.05, choose the correct conclusion regarding the null hypothesis.H0:________________________ Ha:_______________________Compare the p-value and a:_______________Decision:_________________________Conclusion:___________________________________________________________

Choose the correct answer below. O A. Reject the null hypothesis that the percentage of households with more than 1 pet is greater than or equal to 65% when it is actually true. O B. Fail to reject the null hypothesis that the percentage of households with more than 1 pet is greater than or equal to 65% when it is actually false. OC. Reject the null hypothesis that the percentage of households with more than 1 pet is less than 65% when it is actually true. O D. Fail to reject the null hypothesis that the percentage of households with more than 1 pet is less than 65% when it is actually false. Identify the type |l error. Choose the correct answer below. O A.
