Problem 1. Using the data in the xlsx file (attached), create a contingency table (called a Pivot Table in excel) like those in chapter 3. You can use Excel or the apps in artofstat. com. What do you notice from the table? Draw some tentative conclusions.

• What’s the probability of picking a person at random from this sample and having that person be over 50 with normal blood pressure?

• What % of all people are under 30?

• What is the most likely blood pressure for a person over 50?

What kind of variables (quantitative or qualitative) do you have? Could you create a contingency table with different types of variables? Why or why not?

Two pivot tables, one with counts and one with probabilities. Your narrative should include how you created the tables and what you observe.

Explain the difference between counts and probabilities.

A chart that shows the relationship between the two variables. Your narration should include why you chose the chart you did.

Answers to the probability questions including how you calculated the probabilities that you did.

Afarmer sells 9.5 kilograms of apples and pears at the farmer's market. 4/5 of the weight is the apples and the rest is the pears. how many kilograms of pears did she sell at the farmers market

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
