reveals that only 108 get the paper delivered. Using an alpha value of 0.01, what conclusion
can be reached about the claim?

According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.34. Suppose a random sample of 106 traffic fatalities in a certain region results in 48 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the a= 0.01 level of significance? ....

In a survey by Bea et.al., it was found that 218 of 1,062 urban residents had a history of allergic disorder while 728 of 1,000 rural dwellers had no history of such disorder whatsoever. Using an alpha level of 0.10, determine if the proportion of urban and rural residents with a history of allergic disorder are different. Use the seven steps of hypothesis testing.
The company that you work for requires that less than 3% (.03) of the microchips that you deliver are defective. If the percentage is not below 3%, you cannot ship the microchips. You collect a simple random sample of 430 microchips and find that 12 of them are defective. Conduct a hypothesis test with a a =.05 level of significance to determine if less than 3% of the microchips are defective. Write all non-calculation answers in complete sentences. a. Which test would you use and why? b. Write the null and alternative hypothesis in complete sentences. (Make sure you mark which is the null and which is the alternative.) c. Write the null and alternative hypothesis as symbols. d. State the requirements that have been met to run the test. e. What is the test statistic and the p-value? (Make sure you use the right notation.) f. Should you reject or fail to reject the null hypothesis? g. State the conclusion for the test.
A large company that produces a "tat-burner pill claims an average Ioss of 20 pounds in the first month. A consumer advocacy group believes that this claim is actually just "hype" intended to sell more of the compound. The advocacy group Would like to obtain statistical evidence about this issue and takes a random sample of 100 consumers who responded that they had purchased the pill but didn't know what the survey was about. They find that these 100 people lost an average of 18 pounds. Let the standard deviation of the population be 7.5 pounds. Clearly state the hypotheses, obtain the test statistic and p-value, and state the decision and conclusion. Show all your work.
According to the Pew Research Center, 68% of parents have taken away their teen's cellphone and internet privileges "digitally grounding" as punishment to enforce family rules. To verify this, an SRS of 500 teens age 13 to 17 resulted in 355 indicating that their parent(s) had taken away their phone and restricted internet privileges as punishment. Given alpha = 0.05 , is there evidence to support that 68% of teens have been "digitally grounded" by their parents? 18. Write a conclusion using the context of the problem.
Body Mass Index is a measure of body shape. Duran et al. (2013) investigated BMI in Texas youth. In part of the study, they took BMI measurements on samples of 14 year old boys and girls in Texas (94 boys and 98 girls). Suppose they were interested in investigating a possible difference in body mass index between boys and girls at that age. Assume for the purposes of this question that the samples can be thought of as independent simple random samples from 14 year old Texans, and that all other assumptions of the Welch t procedure are met. Welch Two Sample t-test data: BMI by gender = 0.1038 t = -1.6348, df = 189.5, p-value alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -2.9517451 0.2764086 sample estimates: mean in group Boy mean in group Girl 23.30213 24.63980 Give an appropriate interpretation of the confidence interval found in the output. Your interpretation must relate to the problem at hand.

The article "Euthanasia Still Acceptable to Solid Majority in U.S."t summarized data from a survey of 1,025 adult Americans. When asked if doctors should be able to end a terminally ill patient's life by painless means if requested to do so by the patient, 707 of those surveyed responded yes. For purposes of this exercise, assume that it is reasonable to regard this sample as a random sample of adult Americans. Suppose that you want to use the data from this survey to decide if there is convincing evidence that more than two-thirds of adult Americans believe that doctors should be able to end a terminally ill patient's life if requested to do so by the patient.

According to the Pew Research Center, 68% of parents have taken away their teen's cellphone and internet privileges "digitally grounding" as punishment to enforce family rules. To verify this, an SRS of 500 teens age 13 to 17 resulted in 361 indicating that their parent(s) had taken away their phone and restricted internet privileges as punishment.

The U.S. Energy Information Administration claimed that U.S. residential customers used an average of 10,368 kilowatt hours (kWh) of electricity this year. A local power company believes that residents in their area use more electricity on average than EIA's reported average. To test their claim, the company chooses a random sample of 128 of their customers and calculates that these customers used an average of 10,745⁢kWh of electricity last year. Assuming that the population standard deviation is 2198⁢kWh, is there sufficient evidence to support the power company's claim at the 0.05 level of significance? Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.37. Suppose a random sample of 115 traffic fatalities in a certain region results in 56 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the a = 0.1 level of significance? Find the test statistic, zo. zo = 2.59 (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.)
