Give an example of interest to you for comparing two population means. Identify the variable under consideration and the two populations.

Please complete the following question. Make sure you are responding to all parts of the question.    The number of awards earned by students at one high school is recorded. Predictors of the number of awards earned include the type of program in which the student was enrolled (e.g., vocational, general or academic) and the score on their final exam in math.

I want a dataset for my statistics research project. in which i can find at least 3 Quantitative independent variables and one dependent quantitative variable.

Describe when you would use an independent samples t-test versus a dependent samplest-test.

The total cost for a production process is $600 minus two times the number of units produced. The mean and variance of the number of produced are 200 and 20, respectivelySo, the mean and variance of the total cost are A.560,1000 B.80,200 C.180,400 D. 200,600

What is the main purpose of data presentation? Is it applicable for our daily lives? Give specific circumstance that you used data presentation in a real life situation.

Mrs. Kelley noticed a strong positive correlation between the hours students said that they studied for a test and their scores on the test. Which fact would lead you to believe that the relationship between studying and test scores is one of causation and not correlation?

Correlation does not imply causation. What does this mean? Find an example in the media that needs to understand this concept and explain it to your peers. Be sure to include the link to the example you are using.

True or false. When drawing a scatter diagram, the explanatory variable is placed along the vertical axis.
