Using the LinReg(a + bx) command on the TI gives us several values.

  1. What does "a" represent? How do you interpret this number?
  2. What does "b" represent? How do you interpret this number?
  3. What does "r" represent? How do you interpret this number?
  4. In this course, we are less interested in calculating the regression line by hand using a formula than in using technology for the calculation? What advantages does this have? What disadvantages would computing this by hand have?

Linux commands in terminal What processes are running? In the previous task ("Command Based") you were already familiar with the command "ps" which shows some or all of the processes that are running. When you run "ps", you start a new process and you can see the actual process in the output. Later in this task you will use "ps" more. The "top" command also shows an overview of the processes that exist on the system but it the overview...

Does participation in sports, cultural groups, and youth groups improve self esteem for adolescents? What do you think? A study done by McGee et al. (2006) claims that involvement in these groups does improve self-esteem. Following the steps for statistical hypothesis testing, you embark on an independent investigation. For your study, you have randomly selected 100 adolescents with a history of group participation and give them a standardized self-esteem questionnaire. The sample of group-participation adolescents scored a mean of 46.1...

If you run summary() command on a result of linear model fitting returned by lm(), you will see a column Pr(>t). You could guess that it is a result of some t-test. How does it apply here? So far we have seen t-tests in the settings of testing sample locations. The ingredients were: 1) null hypothesis: in earlier cases we looked into the null that stated that two samples came from the distribution(s) with the same mean(s); 2) test statistic:...

4) The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of...

Does the number of years that a woman is on birth control (X) have an effect on how long it takes for her to become pregnant (Y) once she ceases to use it and tries to have children?

A comprehensive employee appraisal is often made up of several different methods of performance evaluation. You can choose to use just one evaluation process when judging an employee's performance, but when you use multiple evaluation methods you are able to get a broader picture of the areas where the employee needs improvement and what recommendations you should make to support employee development. Self-Evaluation The self-evaluation is often effective when teamed up with a performance review. The employee is asked to...
