For a second 6- month period, we used physically guided practice with the same individuals. For each 6-month session, we collected ratings on the level of required assistance (high = bad) for each person. The data for each individual follows (on the next page). Was the assistance significantly reduced in the second 6-month period?

Physical guidance Given your the obtained statistic that you calculated, if you were conducting a hypothesis test on this scenario, what would Step 4 and 5 look like? Since tobt = -2.23 tcrit = -1.761 then we would fail to reject the Null and conclude that the amount of assistance needed with physical guidance was not %3D significantly less than the amount needed with intimidation. Since tobt = -2.23 < tcrit = -1.761 then we would reject the Null and conclude that the amount of assistance needed with physical guidance was significantly less %3D than the amount needed with intimidation. O Since Zobt = -28 < Zcrit= -1.645 then we would reject the Null and conclude that the amount of assistance needed with physical guidance was significantly less than the amount needed with intimidation.

Expert Solution
Step 1

Solution:

23.

The given data is

Statistics homework question answer, step 1, image 1

State the hypotheses.

Null hypothesis:

Statistics homework question answer, step 1, image 2

That is, the amount of assistance needed with physical guidance was not significantly less than the amount needed with intimidation.

Alternative hypothesis:

Statistics homework question answer, step 1, image 3

That is, the amount of assistance needed with physical guidance was significantly less than the amount needed with intimidation.

Dependent t-test is used when two samples are dependent and to test the difference between population means.

Here, the subjects are used for the imitation and physical guidance. Then, paired-t test should be used to test the hypothesis.
