A. Use your calculator. B Since it follows the standard normal distribution, the standard deviation(s) equals to one. S= variance = 1. A. Z= (42-50)/10=-0.8. Enter table A under Z=-0.8. The table entry is 0.2119. This is the area to the left of –0.8. Because the total area under the curve is 1, the area lying to the right of –0.8 is 1-0 ...

Using the calculator, binomcdf (n, p, X) is the cumulative density function of the binomial distribution. So, binomcdf (10, .1, 2) = .9298091736. Binomial mean and standard deviation: If a certain widget has a 75% chance of functioning correctly, then how many should work out of a lot of 100? Logically 75 should work. In fact, the formula for ...
