Consider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide a justification of the statistical method. Provide the appropriate regression model and statistical test when appropriate. Exposure to arsenic in drinking water during pregnancy may have an impact on infant outcomes. Infants born to mothers residing in two cities, one with arsenic concentrations in the drinking water and one without, are compared to investigate whether arsenic exposure is associated with smaller head circumferences. However, the two cities are different with respect to income, prenatal care, parity, and iron supplementation.

What the relationship between descriptive and inferential statistics?

Data can be described as being quantitative or qualitative. If qualitative, it can be described as nominal or ordinal. In order to be ordinal, you must be able to order the data in a meaningful way; therefore, being able to order pins from least to greatest does not make them ordinal, I know.I am wondering though, why can't pins be described as ordinal given they can be ordered in terms of complexity, by the number of repeating digits, etc? EDIT: In this case, the order would be meaningful in a study about links between simple pin numbers and stolen credit cards for instance.

The circle graph shows the number of times a group of survey respondents watched the news in the past week. If the number of respondents in the study was approximately 34,000, how many stated that they watched the news​ 5-6 times in the last​ week? How would you work out this equation to get the answer provided?

C)   The UCC football team has added a national power to next year’s schedule. The other team has agreed to play the game for a guaranteed fee of $350,000 plus 30 percent of ticket revenues. Assume that all tickets will be sold for$25. a)        How many tickets must be sold in order to recover the $350,000 guarantee? b) If college official wish to net a profit of$500,000 from the game, how many tickets must be sold? c)        If a sellout of 50,000 fans is assured, what ticket price would allow the university to earn the desired profit of $500,000? Assuming a sellout of 50,000 tickets, what would total profit equal if the tickets are priced at$25?

In Major League baseball, do Left-Handed hitters and Right-Handed hitters tend to have different batting averages? We will study this question by taking random samples of m=45 seasonal batting averages from left-handed batters and n=53 seasonal batting averages from right-handed batters. The mean batting averages were x= .256 for the left-handers and y=.254 for the right-handers. It is recognized that the true standard deviations of batting averages are σx = .0324 for left-handed batters and σy = .0298 for right-handed batters. The true (unknown) mean batting average for left-handers = μx , while the true unknown mean batting average for right-handers = μy . We would like to examine μx − μy . a) What is the standard deviation of the distribution of x? b) What is the standard deviation of the distribution of x - y ? c) Create a 98% confidence interval for μx − μy ? leftparen1.gif , rightparen1.gif d) What is the length of the confidence interval in part c) ?

To determine:Name the variables, specify for each variable whether it should be treated as categorical or quantitative and give the units for quantitative variables, if available.

As you study Statistics and Probability, dealing with quantitative data is inevitable. As a rule, it makes it extremely difficult to handle such tasks if you do not have correct quantitative data examples.

Have a look at our list of questions where various equations are included. These answers will help you learn the structure and avoid the most common mistakes. Regardless if you need Statistical report for your course or just want to refresh your memory a little bit, these examples will be of help to you!
