Select one of your quantitative variables.
Choose a confidence level (1 – α).
Make a confidence interval for your selected variable. Be sure you show all the steps you took. Include a screen shot of any applet you used in your calculations
Explain your results in everyday language.

Expert Solution

We use alpha = 0.05

Using Minitab Onesample test we can construct 95% Confidence interval for given variable.

Click Stat > Basic Statistics > 1-Sample t... on the top menu, as shown below:

You will be presented with the following 1-Sample t (Test and Confidence Interval) dialogue box:

Click the OK button. The output that Minitab produces is shown below.

you can be 95% confident that mean is greater than or equal to 7740 and less than or equal to 8823.

Hope this will b ehelpful. Thanks and God Bless You :)

A two-variable model involving one quantitative explanatory variable and one categorical (binary) explanatory variable (and no interaction), results in two regression lines that are: A. Always parallel. B. Could be parallel but, depending on the data, may not. C. Never parallel. D. Always horizontal. The two methods of including a binary categorical variable in a regression model are to use indicator coding or effect coding. For indicator coding in the two-variable model (with no interaction): A. The binary variable is coded (-1,1) and the coefficient...

Instructions: Choose a quantitative variable to study, with values such that the range is greater than or equal to 10. An example that you can't use might be "How many pairs of shoes do you own?" Do not give answer choices but use the answers you collect for your data. Note that the range (the largest number of shoes minus the smallest number of shoes) must be greater than or equal to 10. Make a plan that describing the population,...
