Textbook Question
Chapter 9.1, Problem 33DE
Practical Applications. Round to the nearest tenth unless otherwise directed.
General Interest Ocean engineers estimated that the earthquake that hit Japan in 2011 pushed a section of sea floor 250 miles long and 50 miles wide downward by an average of one yard. This movement caused a tsunami. How many cubic yards of water suddenly shifted position? (Express your answer in scientific notation.)

1. Differentiate between discrete and continuous random variables,
providing examples for each type.
2. Consider a discrete random variable representing the number of
patients visiting a clinic each day. The probabilities for the
number of visits are as follows:
0 visits: P(0) = 0.2
1 visit: P(1) = 0.3
2 visits: P(2) = 0.5
Using this information, calculate the expected value (mean) of
the number of patient visits per day. Show all your workings
clearly.
Rubric to follow
Definition of Random variables ( clearly and accurately differentiate between discrete and continuous random variables with appropriate examples for each)
Identification of discrete random variable (correctly identifies "number of patient visits" as a discrete random variable and explains reasoning clearly.)
Calculation of probabilities (uses the probabilities correctly in the calculation, showing all steps clearly and logically)
Expected value calculation (calculate the expected value (mean)…

Calculating probability for the Standard Normal Curve
1.
Assume the mean is zero, the standard deviation is one, and it is associated with the distribution of z values.
Each problem is worth 2 points, 1 point for drawing out the curve and shading the area requested and 1 point
for the answer.
a. What is the P(z > 0)?
b. What is the P(z < 1.0)?
C. What is the P(z <-1.0)?
