State your conclusion, in context. Use a 05 A report on health care in the US said that 28% of Americans have experienced times when they haven't been able to afford medical care. A news organization randomly sampled 801 black Americans, of whom 32% reported that there had been times in the last year when they had not been able to afford medical care.

In a hypothetical scenario, the National Institute of Standards and Technology has received a new replica of The Kilogram. It is weighed five times. The measurements are as follows, in units of micro-grams above 1 kg: 114.3, 82.6, 136.4, 126.8, 100.7. a) Is it possible to estimate the uncertainty in these measurements? If so, estimate it. If not, explain why not. b) Is it possible to estimate the bias in these measurements? If so, estimate it. If not, explain why not.

Given a 95% C.I. = (34.14 mm, 36.02 mm) for a sample of Wooly Bear caterpillar lengths (preceding problem), address the following. Based upon the above information, I am _____ % confident that the 95% C.I. contains the sample mean.
An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age 18 Over Age 18 n1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150 We are interested in determining if the accident proportions differ between the two age groups.
Question 1 A meal supplement provider claims that the average difference in calories between two brands is 55. Provide the following: the null and alternative hypotheses explain whether the hypothesis test is left-tailed, right-tailed, or two-tailed, • explain how you should interpret a decision that rejects the null hypothesis, and • explain how you should interpret a decision that fails to reject the null hypothesis.
In an ongoing nationwide survey, a question asked is whether a respondent favors or opposes capital punishment (the death penalty) for persons convicted of murder. The output for this exercise compares the proportions who said that they were opposed to the death penalty in the year 2008 and the year 1993. Sample X N Sample p 2008 637 1912 0.333 1993 333 1418 0.235 Estimate for p(1) − p(2): 0.098 95% CI for p(1) − p(2): (0.068, 0.129) (a) What proportion of the year 2008 sample was opposed to the death penalty? (Round your answer to three decimal places.) What proportion of the year 1993 sample was opposed? (Round your answer to three decimal places.) (b) What is the estimated difference between the proportions opposed to the death penalty in the 2 years? (Use p2008 − p1993. Round your answer to three decimal places.) (c) Write the 95% confidence interval as it is given in the output. to Interpret this interval in the context of this situation. There is a…

Consider the following studies. Study I: A researcher randomly divided 200 high school students into two groups. The first group was told to not exercise. The second group was told to exercise at least 5 hours each week. At the end of two months, the heart rates of each participant in each group were measured at rest. It was found that the group that exercised 5 hours a week had a significantly lower average heart rate. Study II: A researcher gathered 200 high school students randomly, asked them how long they exercised each week, and then measured their heart rates at rest. It was found that students who exercised at least 5 hours a week had a significantly lower average heart rate. Part A: Which study was experimental? Why? Study IStudy II Part B: List the explanatory and response variables in the studies. Explanatory: heart rate; Response: exercise timeExplanatory: student; Response: amount of exerciseExplanatory: exercise time; Response: heart rate Part C: State whether the…

In an agricultural experiment, the effects of two fertilizers on the production of limes were measured. Nineteen randomly selected plots of land were treated with a brand new fertilizer, and 27 randomly selected plots were treated with an old fertlizer. The number of pounds of harvested limes were measured from each plot. The results are given below. (Round answers to two decimal places.) New Fertilizer Old Fertilizer 486 435 468 423 491 425 470 440 458 423 476 409 456 425 463 443 493 402 501 437 483 420 475 420 456 416 470 435 463 421 473 445 479 422 460 424 467 412 435 427 413 407 420 430 426 430 Find a 90% confidence interval for the difference between the mean weight of the harvested limes.margin of error: lower limit: upper limit: Based on the results, is the new fertilizer better than the old fertilizer? A) Yes, we are 90% confident that new fertilizer is better than old fertilizer. B) No, we are 90%…
