The heights of a group of professional basketball players are summarized in the frequency distribution below. Find the mean height.

Round your answer to one decimal place. 7. The ages of the 45 members of a track and field team are listed below. Construct an expanded stemplot with about 8 rows. 8. Find the variance for the given data. Round your answer to one more decimal place than the original data. Jeanne is currently taking college zoology. The instructor often gives quizzes. 9. Construct a pie chart representing the given data set. The following data give the distribution of the types of houses in a town containing 12,000 houses. 10. Find the median for the given sample data. The ages (in years) of the eight passengers on a bus are listed. 11. A car dealer is deciding what kinds of vehicles he should order from the factory. He looks at his sales report for the preceding period. Choose the vertical scale so that the relative frequencies are represented. Construct a Pareto chart to help him decide. 12. Use data to create a stemplot. The attendance counts for this season’s basketball games are listed below. 13. The frequency chart shows the distribution of defects for the machines used to produce a product. 14. The frequency distribution below summarizes the tar (mg) contains in filtered cigarettes. Overcome knowledge barriers in the realm of statistics by researching, evaluating, and effectively using information to accomplish. Apply the appropriate technological tools in order to compute various statistical measures. Apply ethics and logic to meaningful statistical methods. Analyze and solve statistical problems by applying scientific reasoning. Pick a sports team. Write down their final scores from the last 10 of their games.

Sometimes it’s a single image that sparks a story. Have you ever seen something in your mind’s eye that captured your imagination? Write about it. Make sure to include a description of all the five senses to really set the tone for your piece. Then try broadening your view of the image. Are there people there? What are they doing? See where it takes you. A jewel-encrusted box is found in an ancient abandoned temple. Describe the box, what is in the box, and the temple. Take some time out of your day to people watch. This works especially well in a coffee shop, restaurant, or some other public place where interaction is the norm. Jot down observations about the people around you. Describe a loner, a couple, someone how works in this public area. How do they interact? What’s their body language say about them at this point in time?

How does the employee react to those around him? Write down your first three memories. Are your memories vivid enough to construct a scene from? If not, could you fill in the details? Recall a vivid or perhaps reoccurring dream. Write one page, making the dream as believable as possible. Don’t mention they are dreams. Allow yourself to let go and create a drifting stream of consciousness account. Leave all your notions of punctuation, proper paragraph structure, and logical jumps behind (which if you’re anything like me shouldn’t be hard). This gives you practice for writing surreal scenes and images in a story. Write about a place where two rivers meet. Every family has an anecdote. A short, usually funny story that is told at almost every family gathering. In my family it’s the story of the time when I was three and disappeared from my mother’s side while she was hanging clothes out on the line. Now, I remember this even though I was only three, but I’ve heard the story so many times it’s hard to tell where my memory ends and the story begins.
