1. The problem statement, all variables and given/known data It has been suggested that reaction time to brake a signal from standard brake ligths can be modeled with a normal distribution having a mean of 1.25 seconds and a standard deviation of .46 seconds. What is the probability that the reaction time is between 1. and 1.75. Use your calculator to find the probability. 2. Relevant equations P(a-μ)/σ ≤ z ≤ (b-μ)/σ 3. The attempt at a solution (1-1.25)/.46 ≤ z ≤ (1.75-1.25)/.46 -.5434782609 ≤ z ≤ 1.086956533 I did this part because my notes from my teacher do not tell me how to do this on the calculator. however, I tried in the Z-test section, with my input section on stats. I know where to plug the μ and the σ, but not the 1 and 1.75. x (with a line above it), and a n.
