Study A Use the following description of a research study to answer the next five questions. Researchers were were interested in promoting physical activity within the workplace. They recruited participants to join a team challenge encouraging ways to increase physical activity such as taking active breaks and taking the stairs. Participants either joined as a team or were assigned a team. These teams were then randomly assigned either to be the control group where they just received information about becoming more active or the team-building group, which received the same information as the control group but were encouraged to create a team name and bond as a team throughout the study. One outcome measure of the study was the number of flights of stairs that participants reported taking yesterday. Group Statistics Intervention Mean Std. Deviation Std.

A knewton.com Question The following data was calculated during a study on customer experience. Use the following information to find the test statistic and p-value at a 10% level of significance: • The claim is that the percent of companies that view customer experience as the most vital component of a growing business is different than 50%. Sample size = 50 companies • Sample proportion = 0.40 Use the table or the curve below to find the test statistic and p-value. For the curve select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram, then set the sliders. Use the purple slider to set the significance level. Use the black sliders to set the information from the study described above. z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 |-1.5 0.067 0.0660.064 0.063 0.062 0.061 0.059 o.058 0.057 0.056 -1.40.081 0.0790.078 0.076 0.075 0.074 0.072 0.071 0.069 0.068 |-1.3 0.097 0.095 0.093 0.092 0.090 0.089 0.087 0.085 0.084 0.082 -1.2 0.115…

NEW STUDY: A researcher is interested in the relationship between levels of stress at work and self-reports of overall health. Stress at work is measured on a scale from 0 (no stress at work) to 100 (extreme levels of stress at work). The researcher conducts a study with 11 subjects and determines that the relationship between self-reports of stress and self-reports of overall heath is r = -.41. Which test was conducted for this study? Group of answer choices z-test t-test correlation chi-square
3. A sample drawn from a population has a computed mean of 12,248. A margin of error at 95% confidence was determined to be 19.6. a) Give the 95% confidence interval estimating the actual population mean. b) If the sample size had been 2500: Determine the sample standard deviation. c) If the sample size had been 3600, would the C.I. become wider, or narrower? What is the new margin of error?
