A random sample of 12 students used Method A, and their increase in points averaged 46.31, with a sample standard deviation of 6.44. Another random sample of 10 students used Method B, and their increase averaged 42.79 points, with a sample standard deviation of 7.52. Use the 95% degree of confidence all througH0ut. An appropriate set of null and alternative hypothesis to determine whether Method A increases students points by more than 3 points is:

The null hypothesis is  

The alternative hypothesis is    

Step-by-step explanation:

From the question we are told that

  The mean of method A is

  The standard deviation of method A is  

   The  mean of method B is  

   The standard deviation of  method B  is  

An appropriate set of null and alternative hypothesis to determine whether Method A increases students points by more than 3 points is

The null hypothesis is  

The alternative hypothesis is    

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

squares, rhombus, rectangles
