Question

Consider the following set of data:

	Commerce students (1)	Science students (2)
Sample Size	100	80
Mean	$25.92	$23.67
Standard Deviation	$4.23	$6.09

Calculate the test statistic to determine whether there is evidence of a difference in the population means between Commerce students and Science students.

Give the numerical value of the test statistic correct to 2 decimal places.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
