In a study of the effects of mediation on anxiety, participants were randomly assigned to either engage in a mindfulness meditation session for 5 minutes or to sit quietly for 5 minutes.

Which would be the appropriate null hypothesis? a. H0: u 1 > u 2 b. H0: u 1 = u 2 c. H0: u 1 < u 2 d. H0: u 1 > u 2
Identify the appropriate hypothesis test for each of the following research situations.

Example 2: Bryan coaches track and field at a local high school and during the previous season he got the impression that his 800m runners performed better when their races were in the morning as opposed to the afternoon. This season, he wanted to determine if his runners in fact performed better in the morning so he recorded all of their times for each race throughout the entire season. The data that he recorded for the morning and afternoon races are shown below. Carry out an appropriate hypothesis test at the a = 0.05 level to determine if his 800m runners performed better in the morning than in the afternoon. Sample Size Standard Deviation Average Morning 38 14 122 Afternoon 54 13 124

A popular phone company states that teens only use their phones for 1.5 years or less before upgrading to a new phone. Your mother believes that teens only upgrade after 1.5 years. State the null and alternative hypothesis for the scenario using math symbols and words.
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Suppose that 40% of all supermarkets in the US use recyclable plastic bags. We would like to assess if the proportion of supermarkets in Michigan that use recyclable plastic bags is more than the stated rate. For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.
