Random walk problem. in class we discussed the binomial distribution and used it to calculate the probability distribution for the position of a drunk who takes 10 steps total away from a lamppost, assuming equal probability that s/he steps left or right. this gives rise to a "bell-shaped" distribution akin to the gaussian distribution. in class we calculated the results for positions /- 0, 4, or 8 steps away from the post. suppose the drunk was also a war veteran, and had suffered injuries to her/his left leg, such that s/he stepped to the right with higher probability than to the left. take it as 0.6 probability to the right, and 0.4 to the left. calculate the results for positions /- 0, 4, or 8 steps away from the post, and sketch the resultant distribution. how is this distribution different from the previous one

Step-by-step explanation:

Mathematically;

z-score = x-mean/SD

from the question, we have mean as 29 and standard deviation as 3.6 with z-score as 1.5

So we need to find the z-score here

1.5 = x-29/3.6

3.6 * 1.5 = x-29

5.4 = x-29

x = 29 + 5.4

x = 34.4
