A recent poll has stated that 65% of people need to have their morning coffee to start the day. A researcher wanted to test that claim and found that 65 out of 90 people stated that they rely on their coffee to start their day. At a = 0.01, is the claim stated in the poll believable, based on the survey? Please show all work below, including your null and alternative hypotheses, critical value, test value, and your conclusion.

A December 2014 Pew Research Center poll asked a sample of 1507 adults whether they thought it was important to control gun ownership. A total of 693 of the poll respondents were in support of controls on gun ownership. (a) It the past it was believed that p = 0.48. Test this claim at the a = 0.05 level of significance. Ho: HA: Test Statistic: p-value: Conclusion:

A data set includes data from 400 random tornadoes. The display from the technology available below results from using the tornado lengths​ (miles) to test the claim that the mean tornado length is greater than 2.5 miles. Use a 0.05 significance level. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. What are the test statistic and P-value?

You suspect that drivers for Uber/Lyft have newer cars than a driver who doesn’t drive for Uber/Lyft. Listed below are the ages of cars that you randomly sampled from the streets of Portland. If one were to conduct a hypothesis test for the difference in mean car age and mean Uber/Lyft car age, the conditions for the test would need to be checked. What conditions should you check? Check the conditions and explain how the conditions are met or not. What is the appropriate test to conduct, an independent samples t test or paired t test? Explain.   Uber/Lyft  car age 4 0 8 11 14 3 4 4 3 5 8 3 3 7 4 6 6 1 8 2 15 11 4 Non-Uber/Lyft Car age 8 8 0 3 8 4 3 3 6 11 7 7 6 9 5 10 8 4 3 4

The drug Clarinex is used to treat symptoms from allergies. In a clinical trial of this drug, 2.1% of the 1655 treated subjects experienced fatigue. Among the 1652 subjects given placebos, 1.2% experienced fatigue. Use a 0.05 significance level to test the claim that the incidence of fatigue is greater among those who use Calrinex. This is the equation for Statistics but I don't know what equation to use? Preferrably in a TI84 calculator

A data set includes data from 400 random tornadoes. The display from technology available below results from using the tornado lengths​ (miles) to test the claim that the mean tornado length is greater than 2.8 miles. Use a 0.05 significance level. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. LOADING...

The US Department of Energy reported that 48% of homes were heated by natural gas. A random sample of 317 homes in Oregon found that 166 were heated by natural gas. Test the claim that proportion of homes in Oregon that were heated by natural gas is different than what was reported. Use a 5% significance level. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: P Test Statistic = 0° p-value = H₁: p Based on the hypotheses, compute the following: #v oº 48 48 <-Need answer, please. <-Need answer, please OB 0° Based on the above we choose to Fail to reject the null hypothesis ✓ OB The correct summary would be: There is not enough evidence to support the claim that the proportion of homes in Oregon that were heated by natural gas is different than what the DOE reported value of 48%.
