Question

A journalist is interested in whether there is a significant difference in the salary offered to electrical engineering and chemical engineering graduates at the University of Texas at Austin. She reviews the statistics for starting annual salaries for 2013-2014 and finds the following:
The test statistic is t = 2.4693, with a p-value of 0.0142. Which of the following is an appropriate conclusion?

The samples provide evidence that there is a statistically significant difference between the starting salary of chemical engineering and electrical engineering graduates at the University of Texas at Austin for 2013-2014.
The samples do not provide statistically significant evidence that there is a difference in starting salaries of chemical engineering and electrical engineering graduates at the University of Texas at Austin for 2013-2014.
We cannot use the t-test in this case because the variables (starting salary of engineering graduates) may not be normally distributed.

Answer 1

Answer:

the appropriate conclusion is that

The samples provide evidence that there is a statistically significant difference between the starting salary of chemical engineering and electrical engineering graduates at the University of Texas at Austin for 2013-2014.

Step-by-step explanation:

Since the p-value is small, it indicates statistically significant results. This means that there is a statistically significant difference between the starting salary of chemical engineering and electrical engineering graduates at the University of Texas at Austin for 2013-2014.
