Name the statistical test. A psychologist wants to know if meditating every day helps feel happier. He gathers 20 subjects and gives them a questionnaire and rates them all on how happy they are, on a scale of 1-20. Then he has the same subjects meditate every day for two weeks, and he rates their happiness again to compare it with themean happiness rating from two weeks ago. a. Factorial ANOVA b. One sample z test c. Correlation d. Repeated Measures ANOVA e. Independent groups ANOVA f. Dependent groups/Repeated Measures t tets g. One sample t test h. Independent groups t test

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

cheater

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
