Introduction

Many states have legalized marijuana, and in the next election, more states will vote on this issue. The marijuana economy is massive and legalization of marijuana has vast business consequences. Forbes reported on research from New Frontier, a cannabis analytics firm, which found that federal legalization of marijuana in 2018 could add up to 1 million jobs by 2025 (Zhang, 2018).

Scenario

You are interested in examining how people who think marijuana should be made legal are similar or different from people who think marijuana should not be made legal. You consult the General Social Survey (GSS) 2016 data to examine your hypothesis that people who support the legalization of marijuana are younger than people who do not support legalization of marijuana. Use the following information and data file to test your hypothesis, at an alpha level of 0.05. Report results to three decimal places.

**Fill-in the blanks using information from the scenario and your analyses. When options are given in parentheses, choose most specific correct answer.**

Design of Experiment

1. Independent Variable (IV)= Should marijuana be made legal
2. Dependent Variable (DV)= Age of respondent
3. Will you conduct a one tailed test or two tailed test? ______
4. Do you know the population standard deviation for the DV?______

Hypotheses

Null hypothesis

1. Respondents who support legalization of marijuana are ______(younger/the same age/a different age/older) than respondents who do not support legalization of marijuana.

Research Hypothesis

1. Respondents who support legalization of marijuana are______(younger/the same age/a different age/older) than respondents who do not support legalization of marijuana.

Methods

1. Hypothesis test. A______(z-test/t-test/chi-square)test will be conducted.

Results

**Use p-value = 0.05. When conducting the variance test, the group with thelarger variance must be "variable 1" in order for the resulting F value to be correct. P-values of less than 0.000 should be reported as <0.000. Otherwise, report exact p-values**

1. Respondents who supported legalization of marijuana (n=______) had mean age of______years, with a standard deviation of______years.
2. Respondents who did not support legalization of marijuana (n=______) had mean age of______years, with a standard deviation of______years.
3. The variance in age of respondents who supported the legalization of marijuana (variance =______) was______(thesame/different/smaller/larger)than the variance in age of respondents who did not support legalization of marijuana (variance =______), F=______, p=______.
4. Respondents who supported legalization of marijuana were______(younger/the same age/a different age/older)as respondents who did not support the legalization of marijuana, t=______, df=______, p=______.
