Three cards are randomly drawn from a standard deck of 52 playing cards without replacement. What is the probability of drawing a face card, followed by a 4, followed by an ace? Problem of the Day

Section 11-1 Designing a Study

Classify study types. Design statistical studies. Objectives

Common Core State Standards Content Standards S.IC.3 – Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each. S.IC.5 – Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant. Mathematical Practices 3) Construct viable arguments and critique the reasoning of others. Common Core State Standards

Determine whether the situation describes a survey, an experiment, or an observational study. Then identify the sample, and suggest a population from which it may have been selected. Scientists study the behavior of one group of dogs given a new heartworm treatment and another group of dogs given a false treatment or placebo. Example 1

Determine whether the situation describes a survey, an experiment, or an observational study. Then identify the sample, and suggest a population from which it may have been selected. The yearbook committee conducts a study to determine whether students would prefer to have a print yearbook or both print and digital yearbooks. Example 1

Determine whether each situation describes a survey, an experiment, or an observational study. Then identify the sample, and suggest a population from which it may have been selected. a) A group of high school students is randomly selected and asked to complete the form shown. b) An advertising company wants to test a new logo design. They randomly select 20 participants and watch them discuss the logo. Example 1

Determine whether the situation calls for a survey, an experiment, or an observational study. Explain your reasoning. A research company wants to study smokers and nonsmokers to determine whether 10 years of smoking affects lung capacity. Example 2

Determine whether the situation calls for a survey, an experiment, or an observational study. Explain your reasoning. A national pet chain wants to know whether customers would pay a small annual fee to participate in a rewards program. They randomly select 200 customers and send them questionnaires. Example 2

Determine whether each situation calls for a survey, an experiment, or an observational study. Explain your reasoning. A literacy group wants to determine whether high school students that participated in a recent national reading program had higher standardized test scores than high school students that did not participate in the program. A research department of a retail company plans to conduct a study to determine whether a dye used on a new t-shirt will begin fading before 50 washes. Example 2
