A social psychologist is designing a study to see whether people who see a particular film are more likely to use violence as a solution to a problem. The psychologist plans to use a scale that assesses this construct, which has a population mean of 53 and a standard deviation of 9. The psychologist expects an increase of 6 points above the population mean. Twenty participants will be enrolled in the study, and the data will be analyzed at the .01 level. What is the power of the study?

What is the predicted effect size?

a² + b²= c²

24² + 7² = c²

c= 25

the answer is the third / last answer

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
