Below you will find the dynamic programming recurrence relation that can serve as the basis for a dynamic programming algorithm for solving the problem of finding the -th Fibonacci number . F(n) = 1, if n=1 or 2        = F(n-1) + F(n-2), if n > 2 For each of  the four attempts of writing a dynamic programming algorithm for computing the -th Fibonacci number, please match it to its corresponding statement: (i) a correct bottom-up dynamic programming algorithm, (ii) a correct top-down memoized dynamic programming algorithm, (iii) a correct exponential-time algorithm that does not rely on dynamic programming, (iv) an incorrect algorithm for the problem (i.e., an algorithm that provides an incorrect solution to the -th Fibonacci number).   Pseudocode options for the dynamic programming algorithm for computing the -th Fibonacci number: Match the pseudocodes to the statements above (a)  F: array [1..n] F[1]=F[2]=1for i=3 to n do    F[i]=F[i-1]+F[i-2}return F[n] (b) Initialize an array M[1..n] with 0’scall F(n) function F(i)     {if M[i] =0 then          if (i=1 or i=2) then            M[i]=1      else M[i]=F(i-1)+F(i-2)      return M[i]      }  (c)      call F(n) function F(i)     {if i=1 or i=2, return 1      else  return F(i-1)+F(i-2)      } (d) Initialize an array M[1..n] with 0’scall F(n) function F(i)     {if M[i] >0 then return M[i]              else return F(i-1)+F(i-2)       }     

What is one major difference between a correlational study and an experimental study? 

I empirically collected data of the annual salary and ratings of life satisfaction from a group of people. I found a negative correlation between annual salary and life satisfaction. What does this correlation mean in plain English? (base your answer on this scenario not what you know about the world)

A social psychologist is interested in investigating the effect of social skills training on college students. They take 100 students and then divide these into two groups. Group 1 receives social skills training for 6 weeks while Group 2 does not receive social skills training. Both groups go on with their daily lives and usual routines for the six weeks. At the end of the 6 weeks, the investigators have all 100 students take a social skills test and they compare the average score for each group. What is the Dependent Variable (DV)?
