Please write your respond on separate piece of paper, then take picture and insert the picture(s) in a word document. Then upload the word document. Or you may upload one pdf file. Let's get more familiar with the notation of finding probability from normal distribution (standard normal distribution) as well as the matching graph. For example, if Z is a random variable with standard normal distribution, then for the expression P(1.34 < z < 2.09); this means the lower limit = -1.34 and the upper limit is 2.09. Hence, when using TI84, we can use the function normalcdf(-1.34, 2.09) to calculate this probability. The corresponding graph will be -1 0 2 3 Now it is your turn. With the expressions, please indicate lower limit, upper limit, and normalcdf(lower, upper) and sketch a graph with the area. 1) P(0.78 z < 1.55) 1) P(1.34 < z < 0.52) 1) P(z 1.17) 1) P(z < 0.88)
