A social psychologist wants to test if extroversion is significantly related to a person’s general health. He gets extroversion scores and a measure of general health from the participants’ medical providers. The data are listed below. Higher health extroversion scores mean greater extroversion, while high health scores = good health.
Complete the appropriate statistical test and hypothesis testing using the 4 step approach. State your conclusion in APA format. Alpha level = .05.

r (Using Excel function CORREL(x,y)) = 0.6997
n = 6, Degrees of freedom: df = 6-2 = 4, Level of significance = 0.05
H0: ρ = 0, Extroversion is not significantly related to a person’s general health
H1: ρ ≠ 0, Extroversion is significantly related to a person’s general health
Test statistic: t = r*((1-r*r)/(n-2))^0.5 = 0.6997*((1-0.6997*0.6997))/(6-2))^0.5 = 0.2499
Critical value (Using Excel function T.INV.2T(probability,df))) = T.INV.2T(0.05,4) = 2.7764
Since test statistic is less than critical value, we do not reject the null hypothesis.
So, extroversion is not significantly related to a person’s general health.
