  3. Problem #2 - Demo • Assume that thermometer readings are normally distributed with a mean of 0ᵒC and a standard deviation of 1ᵒC. Draw a sketch and find the probability of the reading. Greater than 2.33 0.0099

  4. Problem #3 - Demo • Assume that thermometer readings are normally distributed with a mean of 0ᵒC and a standard deviation of 1ᵒC. Draw a sketch and find the probability of the reading. Between -2.87 and 1.34 0.9078

  5. Problem #4 – Your Turn! • Assume that thermometer readings are normally distributed with a mean of 0ᵒC and a standard deviation of 1ᵒC. Draw a sketch and find the probability of the reading. Between -4.50 and 1.00 0.8412

  6. Problem #5 – Your Turn! • Assume that thermometer readings are normally distributed with a mean of 0ᵒC and a standard deviation of 1ᵒC. Draw a sketch and find the probability of the reading. Greater than -1.75 0.9599

  7. Problem #6 - Demo • The graph depicts the standard normal distribution with mean 0 and standard deviation 1. 0.1075 1.24

  8. Problem #7 – Your Turn! • The graph depicts the standard normal distribution with mean 0 and standard deviation 1. 0.9418 -1.57

  9. Problem #8 - Demo • Find the indicated value. z0.02 2.05

  10. Problem #8 – Your Turn! • Find the indicated value. z0.005 2.575

  11. Problem #9 - Demo • The Gulfstream 100 is an executive jet that seats six, and it has a doorway height of 51.6 inches. What percentage of adult men can fit through the door without bending given that men’s heights are normally distributed with a mean of 69 in. and a standard deviation of 2.8 in.? z score: 0.0001 Percentage: 0.01%

  12. Problem #10 – Your Turn! • The Gulfstream 100 is an executive jet that seats six, and it has a doorway height of 51.6 inches. What doorway height would allow 60% of men to fit without bending given that men’s heights are normally distributed with a mean of 69 in. and a standard deviation of 2.8 in.? 69.7 inches

  13. Study Tips • Extra Practice Recommendation: Print off the Chapter 6 Review Guide. Practice any problem that you would struggle with if it was on the final.
