For a sample of 48 finance majors, the average time spent reading each issue of the campus newspaper is 19.7 minutes, with a standard deviation of 7.3 minutes. The corresponding figures for a sample of 40 management information system majors are 16.3 and 4.1 minutes. What is the the test statistic, t, with the 0.01 level of significance?

The t-value is ±2.626.

Step-by-step explanation:

An independent sample t-test will be performed to determine whether there is a difference between the average time spent reading each issue of the campus newspaper by finance majors and management majors.

The hypothesis can be defined as follows:

H₀: There is no difference between the two means, i.e.

Hₐ: There is no difference between the two means, i.e.

The test statistic is:

The degrees of freedom is:

The critical value of t is:

*Use a t-table.

**Use the next higher degrees of freedom if 86 is not available.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
