Step-by-step explanation:
The First one and the last one
Answer:
B
Step-by-step explanation:
A. matched-pair t-test is used ot deterrmine whether two samples are different because sometihng has changed and there are two distributions or there is effectively one distribution. In this scenario only mean of two population is being compared and not the effect of any variable
B. two sample t-test is used to determine whether average between two groups is significantly different or not. In this scenario, mean values of two populatinos are being compared.
C. ANOVAD is used to determine whether means of three or more statistically independent groups are significantly different or not. In this scenario, we have only two groups.
D. Chi-squaed test is used to test relationships between two variables. In this scenario, no relationship is being tested.
E. Inference of regression is used to determine how one population of x-values is dependent on another population of y-values based on the each individual sample values. In this scenario, we are not comparing individual values of two population

Hope this helps :)
To find the volume of a cube from its surface area, first use the formula for surface area to find the length of one side of your cube. To do this, plug the surface area you're given into the formula, which is surface area = 6x^2, where x is the length of one side of the cube. Then, solve for x.
The answer is D. You are just adding 8 to the number of hours you work because you earn 8 dollars an hour, or you can just multiply the number of hours by the wage you get paid and you would get the your gross pay. It would also be in quadrant 1 because all the numbers are positive and quadrant 1 is all positive numbers not like the other quadrants where there is either all negative numbers or some positive numbers and some negative numbers. But to make things shorter the answer is D.
