1 Holt McDougal Algebra 2 Surveys, Experiments, and Observational studies How do I focus on the commonalities and differences between surveys, experiments, and observational studies?

2 Holt McDougal Algebra 2 Surveys, Experiments, and Observational studies

3 Holt McDougal Algebra 2 Surveys, Experiments, and Observational studies 1.A sporting goods company is testing a new type of golf club. They want to find out whether the new club makes a golf ball travel a different distance than their old clubs. The results of a random experiment are shown. State the null hypothesis for the experiment. Then use box-and-whisker plots to compare the results for the control group and the treatment group. Do you think there is enough evidence to reject the null hypothesis?

4 Holt McDougal Algebra 2 Surveys, Experiments, and Observational studies 2.An internet provider plans to add a new line to make the internet connection faster. The provider conducts an experiment to see if the new line makes the connection faster. State the null hypothesis for the experiment.
