For the binomical distribution we calculate mean using a equation,
μ = n p
where p is the probability and n is the sample size. Since n=600 and p=0.52 then we obtain,
μ = 600 0.52 = 312
For the binomical distribution we calculate standard deviation using a equation,
σ = n p q
where p is the probability, n is the sample size, and q=1-p since n=600, p=0.52 therefore q=1-0.52=0.48 So, when substitute we get,
σ = 600 0.52 0.48 = 149.76 = 12.24

Decide which of the following statements are true.
-Normal distributions are bell-shaped, but they do not have to be symmetric.
-The line of symmetry for all normal distributions is x = 0.
-On any normal distribution curve, you can find data values more than 5 standard deviations above the mean.
-The x-axis is a horizontal asymptote for all normal distributions.
