1. The weight of a female California bobcat is normally distributed with population mean = 19 pounds and population standard deviation = 3.5 pounds. What proportion of the (female) bobcats weigh less than 24 pounds?

2. Same data as problem 1 (population mean = 19 pounds and population standard deviation = 3.5 pounds): what proportion of the (female) bobcats weigh between 12 to 26 pounds?

3. Same data as problem 1 (population mean = 19 pounds and population standard deviation = 3.5 pounds): what proportion of the (female) bobcats weigh more than 28 pounds?

4. Same data as problem 1 (population mean = 19 pounds and population standard deviation = 3.5 pounds): find Q1 (the 25th percentile). Remember that 25% (0.25) of the data will be less than Q1.

5. In the standard normal distribution ( = 0, = 1) what boundary value z gives you 0.03 in one tail? Either the positive or the negative value is acceptable.
