Estimate the distance traveled in 20 seconds given the following sample velocities using right- endpoint values. Be sure to write the units for your answer. Time (s) 10 15 20 Velocity (m/s) 3 3.4 2.9 2.4 1

Using the standard normal table in the Toolbox, determine a Z-value. Each response must include three numerical values and be rounded to the hundredths place. Question 1 The cumulative area to Z is 0.80.  Question 2 The cumulative area to Z is 0.1762.  Question 3 The area between Z and negative infinity is 0.6664.  Question 4 The area between Z and positive infinity is 0.119.
