assume that thermometer reading are normally distributed with a mean of 0 degrees celsius and a standard deviation of 1.0 degree celsius. a thermometer is randomly selected and tested. Find the probabilities below assume Z represents the same ransom variable as the scenario above. P(Z< -2.5) and P(Z >1.96) Solution NORMAL DISTRIBUTION, STANDARDIZED VARIABLE z, PROBABILITY \"LOOK- UP\" STANDARDIZED VARIABLE: z = (x -.
