A random sample of 12 students used Method A, and their increase in points averaged 46.31, with a sample standard deviation of 6
Kitty [74]

Answer:

The null hypothesis is   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3  

Step-by-step explanation:

From the question we are told that

  The mean of method A is \mu_A =  46.31

  The standard deviation of method A is  \sigma  = 6.44

   The  mean of method B is  \mu_B   =  42.79

   The standard deviation of  method B  is  \sigma_B  =  7.52

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   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3
