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 $H_a : \mu_A - \mu_B > 3$
