1. Define own words the following terms: a. Probability. b. Standard normal distribution. c. Continuous Random Variable. 2. Use the z-table to look up the corresponding values for the following tabulated z-score and probability values: a. z = 2.140 b. z = 2.965 c. z = - 0.950 d. z = - 2.255 e. p = 0.1423 f. p = 0.9915 3. The average lethal blood concentration of morphine is estimated to be 2.5 g/mL with a standard deviation of 0.95 g/mL. The data is normally distributed. Examine the range of values 0.05 to 4.95 g/mL. Answer the following questions and provide the appropriate calculations: a. What is the probability associated with the range lethal morphine blood levels? b. Provide the range of values that lie within 1, 2 and 3 standard deviations from the mean. c. What is the probability that somebody dies if the blood morphine concentration is 0.3 g/mL
