The purpose of this study was to demonstrate that soy beansinoculated with nitrogen-fixing bacteria yield more and growadequately without expensive environmentally deleterioussynthesized fertilizers. There were 8 inoculated plants and 8 un-inoculated plants. The plant yield as measured by pod weight (ingrams) for each plant is given in the table below.Sample number Inoculated Un-inoculated11.760.6621.450.8531.231.0041.531.4452.341.016.1.960.7571.791.5181.210.92The initial hypothesis was that inoculated plants wouldoutperform their un-inoculated counterparts. What is your overallimpression concerning the pod weight in the two groups?

Calcium is the most abundant mineral in the body and also one of the most important. The recommended daily allowance (RDA) of calcium for adults is 800 milligrams (mg). A random sample of 18 people with incomes below the poverty level gives the following daily calcium intakes: 686, 433, 743, 647, 734, 641, 993, 620, 574, 634, 850, 858, 992, 775, 1113, 672, 879, 609 At the 1% significance level, do the data provides sufficient evidence to conclude that the mean calcium intake of all people with income levels below the poverty level is less than the RDA of 800 mg?

To improve fuel efficiency and reduce pollution, the owner of a trucking fleet decides to install a new fuel catalyst in all his semi-trucks. Before the installation, his trucks had a mean of 5.6 miles per hour. A random sample of 12 trucks after the installation gas the following gas mileage: 5.9, 6.7, 6.9, 6.4, 6.6, 6.3, 6.2, 5.9, 6.2, 6.4, 6.6, 5.6 a) Test if fuel catalyst is effective in increasing miles per gallon at alpha = 0.05 level of significance. State the conclusion. b) Find 99% confidence interval for the true mean increasing miles per gallon. State the conclusion.
Genetic drugs are lower cost substitutes for brand-name drugs. Before a genetic drug can be sold in the United States, it must be tested found to perform equivalently to the brand-name product. The U.S. Food and Drug Administration is now supervising the testing of new genetic antifungal ointment. The Brand-name ointment is known to deliver a mean of 3.5 micrograms of active ingredient to each square centimeter of skin. As part of the testing, seven subjects apply the ointment. Six hours later, the amount of drugs that has been absorbed into the skin measured. The amounts, in micrograms, are 2.6, 3.2, 2.1, 3.0, 3.1, 2.9, 3.7 How strong is the evidence that the mean amount absorbed differs from 3.5 micrograms? Test by using a confidence interval with ?=0.05α=0.05. Show Step1-Step3. Round critical value to nearest hundredth. (e.g. 0.1256 would be entered as 0.13) Round confidence interval to nearest thousandth. (e.g. 0.12456 would be entered as 0.125)
Getting an adequate amount of sleep can improve a variety of physiological functions, and it is known that the average number of hours that people sleep each night is normally distributed. A psychiatrist or a major research center takes an SRS of 25 emotionally disturbed patients and records the average amount of sleep that each gets on a typical night. He summarizes the data and finds that Xbar=6.90 and S= 0.878. What sample size would the researcher need to use in order to decrease the margin of error of a 95% confidence interval to +-0.20 hours?
