Use Excel to test. For each paired difference, compute After – Before. In Data Analysis, t-Test: Paired Two Sample for means, select the After data for Variable 1 Range. Note that the critical value output by Data Analysis for this test is always positive. In this problem, the sign of the critical value is negative corresponding to 1-tailed test with lower reject region and negative lower critical value.

What is your conclusion?
A. Do not reject the NULL Hypothesis because the actual value is greater than critical value
B. Reject the NULL Hypothesis because the actual value is less than the critical value
C. Reject the NULL Hypothesis because the actual value is greater than critical value
D. Do not reject the NULL Hypothesis because the actual value is less than the critical value

(General guidance: in responding to the following four questions, do not simply provide pseudo-code. Rather explain the main insight in such a way that an experienced programmer could devise an implementation of the algorithm on the basis of your explanation. Indeed, pseudo-code may not be necessary at all.)
Give an algorithm that takes as input a string and returns the length of its longest palindromic subsequence.
