At a bakery, a researcher stands at the counter where orders are placed and watches to gather information about what customers are purchasing. This is an example of:

A research team has been contracted to learn some information about the donuts sold at a bakery.  Choose the name that best fits the scenario.   The research team received a list of individuals who purchased donuts from the bakery. The team numbered all of those individuals and then chose every fifth name on the list to gather information about the donuts being sold.

In a high school math class, tests are counted as 75% of the grade, quizzes are counted as 15% of the grade, and homework is 10% of the grade.  If a student has a test average of 91%, a quiz average of 85%, and a homework average of 98%, what is the student’s grade?  Round to the nearest tenth… one place to the right of the decimal and do not include a percent sign.  [Answer1]

At a bakery, a researcher stands at the counter where orders are placed to gather information about what customers are purchasing.  The research gathers information from every tenth customer.   This is an example of:

A research team has been contracted to learn some information about the donuts sold at a bakery.  Choose the name that best fits the scenario.   The research team tells the bakery that their information will be gathered from every person (that’s all persons) who purchases donuts.

Use the following table to answer the questions below. You do not need to simplify your fractions. The table shows the results of a survey of 200 people about which diner in town they prefer and what meal they prefer to eat at that diner. Report the answers as fractions and do not reduce the fractions.  You will be filling in the numerator for the probability in the first blank and the denominator for the probability after division sign in the second blank.
