Question

An experiment is conducted to determine whether glue type and/or drying temperature affect the bond strength of the connection between two phone parts. Three different types of glue (A, B, and C) and two different temperatures (90o and 110o) will be used. There will be 3 sets of partstested at each treatment combination.

What is the response of interest?

List the factor(s) and whether they are categorical or continuous.

List the levels for the factor(s).

List the treatment combinations.

What is the experimental unit? What is the observational unit?

Use the cars 2004 dataset to do the following:

Select only the SUV’s (SUV?=1). Using a boxplot, graph the MSRP.

Describe the shape of the dataset, according to this boxplot.

According to the boxplot, are there any outliers? Explain your answer.

The center line for the boxplot stands for which statistic? What is the approximate value of this statistic?

Using the full dataset and a histogram, graph the variable Weight.

Describe the shape of the histogram.

From what you see on the histogram, are there any outliers? Explain your answer.

Create a side-by-side boxplot of the variable Weight, comparing the Minivans to the other cars.

Fully compare and contrast these boxplots.

Using the complete dataset and the variable “Dealer Cost”

Form a stem and leaf plot, a boxplot and a histogram. For each of the three graphs, list the advantages and disadvantages of using each to display this dataset.

For this dataset, which would you select as the best method of these 3 to use?

Explanation / Answer

Dear student, I am only answering the first question as per Chegg Guidelines.

The response variable of interest is the bond strength.

There are 2 factors, temperature and type of glue. Temperature is continuous and type of glue is categorical.

The levels of temperature are 90 degrees and 100 degress and the levels of type of glue are A,B and C.

Treatement Combinations are (90, A) (90, B) (90, C) (100, A) (100, B) (100, C)

Experimental as well as observational unit is the bond strength.
