Scenario: A study by Blackwell, Trzesniewski, and Dweck (2007) measured mindset of junior high students at the beginning of 7t grade, then measured the student's grades in their math class (out of 100-point scale) at the end of 7th grade and at the end of 8t grade. The sample size, mean, and standard deviation of these math grades for 7th grade and gth grade are provided in Table 1. Mindset was measured ona 1- 6 Likert scale from Strongly Disagree (1) to Strongly Agree (6), so higher scores are related to high levels of growth mindset (the understanding that learning from mistakes and persevering leads to success). To make the sample sizes more similar, you will be comparing the junior high students with Fixed Mindset (an average score of 3 or below) to those with mixed mindset (an average score of 3to 4 points). Compare the math grades for each grade for students with fixed mindset with those with mixed mindset to answer the following research question: Research Question: Does mindset matter? In other words, do students with fixed mindset get worse grades than students with a more mixed mindset? D Question 18 1 pts State the null hypothesis for the 8th graders in symbols.
