1. Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the probability that a randomly selected thermometer reads greater than −1.59 and draw a sketch of the region.

2. Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the probability P(−0.45<z<0.45)​, where z is the reading in degrees.

P(−0.45<z<0.45)=____________

The number of minutes spent reading in one day is normally distributed with a mean of μ = 23 and a standard deviation of σ = 5. How much time would you have to spend reading in a day to find yourself in the top 10% of readers?

Assuming that the thermometer readings have a normal distribution with a mean of 0 °C and a standard deviation of 1 °C, what is the probability of getting a reading between 1.50 and 2.25?
