Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148

Step-by-step explanation:
I could see if I can help but I don't know where the question or the table is.
An easy way to do this is to plug in your answer choices in the correct variable places.
A - 1,5 so 3 (5) -2 = 13 // 8 (1) + 5 = 13
Therefore does 13 = 13? Yes
B. 3,9 so 3 (9) -2 = 25 // 8 (3) + 5 = 29
Therefore does 25 = 29? NO, so choice B is out
C.-4,9 so 3 (9) -2 = 25 // 8 (-4) + 5 = -27
Does 25 = -27? NO, so C is out
D. -2,3 so 3 (3 )-2 = 7 // 8 (-2) + 5 = -11
Does 7 = -11? NO, so D is out
YOUR ANSWER IS A
