A nurse is interested in whether there is a relationship between daily levels of stress and likelihood of a heart attack. The stress scores (predictor variable) and risk of heart attack values (criterion variable) from a small sample of participants are depicted below.

Stress Score (higher values = more stress) 7,4,6,6

Risk of Heart Attack (higher values = greater risk) 2,8,0,5

What is the numeric value of the slope (b)?

A researcher investigates whether daily exercise decreases long-term stress levels. On a national survey, the mean stress level of those who do not exercise is 8.5. The stress score rating is 0 to 10, whereby higher scores are associated with higher stress levels. The researcher recruited nine (9) participants who exercised daily for two weeks and recorded the following stress scores: 5, 5, 4, 3, 6, 2, 9, 4, 6 Showing calculations where necessary: a) State the null and the...

INDEPENDENT SAMPLES T-TESTS A researcher was interested in testing whether alertness levels differed in those who drank a cup of coffee versus those who drank an energy drink. She randomly assigned participants to one of the two conditions and then showed them a five-minute video. After the video, all participants completed a questionnaire measuring their memory for things that had been presented in the video. Higher scores = better recall. Perform an appropriate two-tailed test of the significance of the...

A researcher is studying the relationship between thyroid hormone levels and smoking. A sample of 100 nonsmokers had a mean hormone level of 120ng/dl with a standard deviation 40ng/dl, while a sample of smokers had a mean hormone level of 110ng/dl with a standard deviation 35ng/dl. A randomly selected individual from the nonsmoking group had a hormone level of 126, while a randomly selected individual from the smoking group had a hormone level of 115. Find the corresponding z-scores. Which...

Problem Set 2: Linear Regression Analysis Research Scenario: A social psychologist is interested in whether the number of days spent in a refugee camp predicts trauma levels in recently resettled refugees. He interviews 17 refugees to determine how many days they spent in a refugee camp before being resettled, then administers the Harvard Trauma Questionnaire Part IV (HTQ Part 4), where a higher score indicates higher levels of trauma (Mollica et al., 1992). He compiles the information in the table...
