Question 1076677: For a standard normal distribution with mean of 0 and standard deviation of 1, what is P(-0.3≤x≤0.4)?
If a normal distribution has a mean of 17 and standard deviation of 4, what is P(x≥16)?

You can put this solution on YOUR website! For a standard normal distribution with mean of 0 and standard deviation of 1, what is P(-0.3≤x≤0.4)?:::: normalcdf(-0.3,0.4) = 0.2733
----------------------------------------------
If a normal distribution has a mean of 17 and standard deviation of 4, what is P(x≥16)?
z(16) = (16-17)/4 = -1/4
P(x>=16) = P(z >= -1/4) = normalcdf(-1/4,100) = 0.5987
