Chang works for NASA designing planetary rovers. For his current project, he has to design a rover capable of withstanding the harsh climate on the surface of Venus. As part of his design work, Chang models the daily high surface temperature of Venus using a normal distribution with a mean of 465 °C and a standard deviation of 25 °C. Use this table or the ALEKS calculator to find the percentage of daily high temperatures between 505 °C and 535 °C according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). 0% S
