For a standard normal distribution, find: P(-1.38

For a standard normal distribution, find: P(-1.38 < z < -1.23) HINT: Recall that for spreadsheet programs like Excel or LibreOffice.org, you can use =normdist(x, mean, stdev, 1) to find cumulative normal probabilities. If you wanted to find the probability between two values x_l and x _2, you could subtract the smaller cumulative probability from the larger: =normdist(x_2, mean, stdev, 1) - normdist(x_l, mean, stdev, 1)
