Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find P62, the 62-percentile. This is the temperature reading separating the bottom 62% from the top 38%.
A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1537 and the standard deviation was 315. The test scores of four students selected correspond to each value. random are 1920, and 1260. Find the z-scores that The z-score for 1920 is. (Round to two decimal places as needed.) The z-score for 1260 is (Round to two decimal places as needed.)

A California lake has been stocked with rainbow trout. These trout have an average length of 24 inches, with a standard deviation of 3 inches. Someone goes fishing and catches a trout that is 26.25 inches long. Express the length of this trout in standard units, relative to all the trout that were used to stock the lake. Choose the answer below that is closest.
