    MHB Probability & Central Limit Theorem

    This is what I have so far. σx = σ/ √n = 1.2/ √35 = 0.2028 z = x̄ - μx̄/σx = x̄ - μx̄/σ/√n = 12,749 - 12,752/ 1.2√35 = -0.4226 = .33724 I stopped right there because I got confused. I'm stuck. OTE=greg1313;90547]Hello rihnavy :D We ask that our users show their progress (work thus far or...

    MHB Probability & Central Limit Theorem

    [FONT=Arial Black]The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. μx̄ = μ = 12,749 σ = 1.2 n = 35 For the given sample n = 35, the probability of a sample mean being less than...
