An environmentalist estimates that the mean amount of waste recycled by adults in the United States is more than 0.75 pound per person per day. You want to test the claim. You find that the mean wasted recycled per person per day for a random sample of 16 adults in the United States is 0.8 pounds and the standard deviation is 0.21 pound. At a = 0.05, can %3! you support the claim?

Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma. Over a period of months, anadult male patient has taken eight blood tests for uric acid. The mean concentration was ?̅= 5.35mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, withσ = 1.85 mg/dl.a. Find a 90% confidence interval for the population mean concentration of uric acid in thispatient’s blood. What is the margin of error?b. Find a 99% confidence interval for the population mean concentration of uric acid in thispatient’s blood. What is the margin of error?c. Compare the margins of error for parts (a) and (b). As confidence levels increase, do marginsof error increase?

It takes an average of 9.4 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 49 injured patients to immediately tell the truth about the injury and noticed that they averaged 9.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 0.94 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer ? H1: ? Select an answer c. The test statistic ? O (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? O a f. Based on this, we should Select an answer a the null hypothesis. g. Thus, the final conclusion is that. |(Please show your answer to 4 decimal places.) The data suggest the populaton mean is significantly less than 9.4 at a = 0.01, so there is…

It takes an average of 11.9 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will increase if the patient is immediately told the truth about the injury. The EMT randomly selected 47 injured patients to immediately tell the truth about the injury and noticed that they averaged 12.4 minutes for their blood to begin clotting after their injury. Their standard deviation was 4.09 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b.
