For the following five questions, use the formula and your t-Test table in Appendix B2. Use the following study set-up: A researcher is interested in seeing if negative political ads against an opponent (group one) are more effective than positive ads for the original candidate (group two. If the mean for group one is 7.00, the mean for group two is 10.00, the n for group one is 20, the n for group two is 20, the variance for group one is 2.50, and the variance for group two is 4.5 What is t? a. 4.5
b. 0.5916
c. 250
d. 507
e. None of the above

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
