a) Between z = 0 and z = - 2.07

b)To the right of z = 0.23

c) Between z = -1.53 and z = -2.08

2. Find the probabilities for each, using the standard normal distribution.

a) P(-1.23

b) P(1.12

c) P(z > 1.43)

3. Find the z value that corresponds to the given area:

4. Find the z value to the right of the mean so that 54.78% of the area under the distribution curve lies to the left of it.

5. An adult has on average 5.2 liters of blood. Assume the variable is normally distributed and has a standard deviation of 0.3. Find the percentage of people who have less than 5.4 liters of blood in their system.

6.The average time spent by construction workers on weekends is 7.93 hours (over 2 days). Assume the distribution is approximately normal with a standard deviation of 0.8 hours.

a.Find the probability that an individual who works at that trade works fewer than 8 hours on the weekend
