The correct answer for the question that is being presented above is this one: "0.5" <span>The probability that a normal random variable is less than its mean is 0.5. In a normal distribution, 1.0 refers to the one that is stable and is in equilibrium.</span>
The sample is not randomly chosen. if you call every tenth person in a sample of 40 people then you have 10, 20, 30, 40 and your sample is 4 people that seems pretty small. I hope this helps :) . Have a nice day!
