>there is a difference between the two poulation means.

>there is only a positive idifference between the means.

>there is only a negative difference between the two populations.

6. The alternative hypothesis would be:

>test scores will be higher for the group using the new reading materials.

>test scores will be lower for the group using the new reading materials.

>there is no difference between the two population means.

>cannot determine.

    Given X, and x, distributions that are normal or approximately normal with unknown o, and on, the value of t corresponding to X, - X, has a distribution that is approximated by a Student's t distribution. We use the convention that the degrees of freedom is approximately the smaller of n - 1 and n, - 1. However, a more accurate estimate for the appropriate degrees of freedom is given by Satterthwaite's formula: 2 2 xn2 522 +$22) d.f. z...
