Answer:
The test statistic value is, <em>t</em> = -5.245.
The effect size using estimated Cohen's d is 2.35.
Step-by-step explanation:
A paired <em>t</em>-test would be used to determine whether the remedial tutoring has been effective for the statistics tutor's five students.
The hypothesis can be defined as follows:
<em>H</em>₀: The remedial tutoring has not been effective, i.e. <em>d</em> = 0.
<em>Hₐ</em>: The remedial tutoring has been effective, i.e. <em>d</em> > 0.
Use Excel to perform the Paired <em>t</em> test.
Go to Data → Data Analysis → t-test: Paired Two Sample Means
A dialog box will open.
Select the values of the variables accordingly.
The Excel output is attached below.
The test statistic value is, <em>t</em> = -5.245.
Compute the effect size using estimated Cohen's d as follows:
Thus, the effect size using estimated Cohen's d is 2.35.
Answer:
Step-by-step explanation:
Sin theta is the ratio of side opposite over hypotenuse of a reference angle situated at the origin in an x-y coordinate plane. If sec theta is negative, then the only quadrant where sin is positive AND sec is negative is quadrant 2. Remember that sec theta is the inverse of cos theta. Puttling our right triangle in QII, the side measuring 7 is across from the angle and the hypotenuse is 11. In order to find the cos theta and tan theta, we need the side adjacent to the angle. Use Pythagorean's Theorem to find the side adjacent.
and
and
so
Remember that this value is why the sec is negative. Because x is negative in QII, the cos theta is side adjacent over hypotenuse:
and
But we should probably rationalize that denominator, so
