Find the area under the standard normal to the right of z = -1.50 and to the left of z = 2.50 (Round answer to the nearest ten-thousandths.)
Find the z-score for the standard normal distribution where: P(-a<z<0) = 0.1844 please explain or show work
For the standard normal distribution mean = 0 and standard deviation = 1 find: P(z < 2.95) Draw a labeled normal curve
Please show the work !

5. Use the Standard Normal Distribution table to find P (Z<-0.69)
A. Use Minitab Express to construct a standard normal distribution to find the proportion of the curve above z = 2.50. Copy+paste your distribution here and clearly identify your final answer. Please show a screenshot of your minitab screen. B. Use Minitab Express to construct a normal distribution with a mean of 500 and standard deviation of 100 and find the area above x = 750. Copy+paste your distribution here and clearly identify your final answer. Please show a screenshot...
