In chapter 1, we learned that income can be either a continuous or discrete depending on how the question is asked.Give an example representing a discrete probability distribution and another example representing a continuous probability distribution. Explain why your choices are discrete and continuous.

Quantitate Methods Probability Distribution & Normal Distribution Module Goals After completing this module, students will be able to do the following: ⦁ Demonstrate ability to create an Excel spreadsheet and preform statistical calculations in Excel. ⦁ Differentiate what a question is asking and what statistical calculation to use in order to answer the question. ⦁ […]

The local news reported that 6% of U.S. drivers text on their cell phones while driving.  If 300 drivers are selected at random, find the probability that exactly 25 say they text while driving.   Be sure and use the continuity correction for the normal approximation to the binomial distribution.

1.    It is very important to be able to find probabilities for a given z score.  Using software or a Standard Normal Distribution table, determine the following probability for the area (15 points) a.    between z = -0.52 and z = 2.33 b.    z > 1.65 c.    z < 1.85 d.    z < 0 e.   […]
