A researcher collected data from male and female Caucasian, African American, and Hispanic graduate students using quantitative measurs of extraversion, academic self-efficacy, dissertation anxiety, and math anxiety, each on a scale of 0 to 100 with higher scores indicating more of the specific latent attribute (e. g., more anxiety). Each participant was also asked if they intended to conduct a qualitative or quantitative dissertation study and how many months they estimated it would take to finish the dissertation. Dissertation anxiety and number of months to finish a dissertation are not related.

a. Correlation
b. Paired samples t test
c. Analysis of Variance (ANOVA)
d. Multiple linear regression
e. Chi square test of independence

a. Correlation

Step-by-step explanation:

Correlation is the measure of the degree to which any two variables vary together.In simple words two variables are correlated if they vary simultaneously in some direction.

We have two variables here . One is the measure of anxiety and the other is the number of months.

Paired sample t- test is conducted when we have the paired data. So this option is incorrect.

ANOVA is used for determining the total partitions or total variations.

Multiple Linear regression is used for indpendent variables.

Chi square distribution contains only one variable .

So the correct answer is option a.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
