Researchers working for Kaiser want to know if there is a relationship between smoking and diabetes. They sample 900 patients at random from the population of patients who are 18 and older. In the sample, there are 145 smokers. Of these, 54 have no diabetes, 72 have pre-diabetes, and 19 have diabetes. Among the nonsmokers, 527 have no diabetes, 160 have pre-diabetes, and 68 have diabetes. (a) What is the null hypothesis the researchers might want to test, and what is the appropriate test statistic? 344 (b) Make a table to represent the data. 345 (c) Carry out the test and state your conclusion. 346 (d) The table we made to summarize the data does not clearly present the relationship between smoking and diabetes. Can you think of a way to modify it to make the relationship clearer? 347 (e) What kind of study is this? Explain what the result of the hypothesis test means in light of the limitations of this study.Provide step by step details and explanations.

Researchers have looked for a possible relationship between marijuana smoking and a deficit in performance on a task that measures short-term memory. The memory test utilized in the research was the digit-span task from the Wechsler Adult Intelligence Scale (WAIS). Two groups of ten subjects were tested on the memory task. One group claimed to have never smoked marijuana and the other group claimed to smoke marijuana regularly. The following data is the participant’s scores on the memory task: Non-Smokers ...

2 Systolic Blood Pressure & Heart Rate Researchers want to know if there is a relationship between systolic blood pressure and heart rate in the population of all ICU patients. They collected data from a sample of 200 ICU patients and computed a correlation of r = -0.057 between systolic blood pressure and heart rate. StatKey was used to construct a 95% confidence interval of [-0.212, 0.098] for the population correlation. If researchers wanted to conduct a hypothesis test to...

Scenario: The researhers want to know if there is a relationship between the number of cars sold and revenues in hopes of developing a predictive model in the near future. Below is the number of cars sold and revenue generated for 6 automotive dealerships. You're expected to create a SCATTERPLOT diagram, then insert a line of best fit and the regression equation. Company Cars (in ten thousands) Revenue (in billions) A 63 7 B 29 3.9 C 20.8 2.1 D...

You want to know if there is a relationship between surgeons’ surgical experience and surgical site...

You want to know if there is a relationship between surgeons’ surgical experience and surgical site infection (SSI) rates. Since SSI’s are relatively rare (infections develop in roughly 1-3 of every 100 patients who have surgery), you decide to do a case control study in which you select hospital patients who experienced a SSI and hospital patients who did not, and compare patients’ exposures to surgeons with <10 years of experience, and >10 years of experience. Assume you have access...

I want to know the relationship between inventory turnover ratio and allowance for obsolescence in inventory....

I want to know the relationship between inventory turnover ratio and allowance for obsolescence in inventory. Basically, I am analyzing a company's financial statement, and this company is in bad position, high leverage (borrowed 1B last year), one of the sector filled chapter 11, and there are many other bad signs. Therefore, I thought the inventory turnover ratio in 2016 would be better than 2017's, however, it came out to be 2017's inventory turnover ratio was little bit higher than...

Researchers want to know if playing violent video games increases aggression levels. They know that the typical teenager scores an average of μ = 4 on a test of aggression. To evaluate their hypothesis, they take a random sample of n = 5 teenagers and have them play violent video games for two hours. After playing the games the teenagers then are measured with the aggression test, resulting in the following scores: X 7 6 4 5 5 (a) Identify...

There are researchers who want to know if M poisoning in mice is less extreme in males. An SRS of one hundred male mice and an independent SRS of one hundred female mice are obtained. The male mice had a sample mean of thirty-nine and a sample standard deviation of eight. The female mice had a sample mean and standard deviation of 40 and 10, respectively. Let u1 represent the true mean response for the males and u2 represent the...

A team of researchers has developed a new weight loss supplement. They want to know if patients who use the new supplement for four weeks lose any weight. The supplement has some minor side effects including mild headaches and achiness. If the researchers obtain evidence of weight loss they will proceed to produce the supplement commercially and sell it for a large profit. If they do not obtain evidence of weight loss, the project will be ended. State the null...

To understand the implications of expanding health coverage, researchers want to know if people with health insurance use more health care than do people without it. To test this, they leveraged an administrative lottery that randomly assigned individuals to either receive public health care or not. Using the data below on the number of medical interactions (e.g., hospital visits or doctor appointments), test whether individuals with health insurance use health services differently than do those without it (alpha=0.1, two tails).No...
