Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Transcribed Image Text:(Problem for Questions 17 - 19). Research has shown that when children and adolescents
have contact with peers of a different race or ethnicity, this decreases the likelihood of
racial/ethnic discrimination (Pettigrew & Tropp, 2008). In a study my colleagues and I
conducted we examined the extent to which children had friendships with peers of a different
race or ethnicity and whether that increased the likelihood to intervene when a peer was being
bullied because of their race or ethnicity. So in a sample of early adolescents we measured
how many friendships with peers of different races or ethnicity participants had (on a scale of 1
= none to 4 = Many) and how likely they were to say something to their classmates who were
bullying another classmate because of their race and ethnicity (on a scale of 1 = Really not
likely to 6 = really likely). Here is data from a subsample of participants:

Transcribed Image Text:We were wondering whether friendship contact would statistically significantly predict the
likelihood to intervene in a bullying incident that was based on race or ethnicity. What would the
regression line for this prediction model be? Fill in the blanks and round answers to 2 decimal
points.
