A study was conducted to examine the factors that affect a student's confidence on a multiple-choice mathematics exam. Gender, exam score (out of 100 points), and confidence rating (on a scale from 1 to 6) were recorded for each Intermediate Algebra student in a random sample. These data can be found in the file MathSelfEfficacy.xlsx. You will perform a linear regression using the confidence rating (Confidence) as the explanatory variable and the exam score (Score) as the response variable. For the math self-efficacy study, what can you say about the appropriateness of using simple linear regression to model these data? Group of answer choices Simple linear regression is not appropriate for these data. Simple linear regression is appropriate for these data if there is a significant linear relationship. If simple linear regression is used for these data, the results will not be reliable
