For a Normal distribution with μ=10.6 and σ=2.6, what proportion of observations have values greater than 5?

Is there a way I can calculate this on my graphing calculator? I know the answer to the problem but I can't seem to solve this correctly, I think my formulas may be off or I am missing a step.

Expert Solution

μ=10.6 and σ=2.6

x = 5

z = (x - µ)/σ = (5 - 10.6)/2.6 = -2.15

P(z > -2.15) = 0.9844

Steps:

Go to STAT > 1.

Please give me a thumbs-up if this helps you out. Thank you!
