In a study of jury behavior, Dr. Marek will obtain two samples of participants and give them details about a trial in which the defendant was obviously guilty. Although both groups will hear the same details during the trial, one group will be told that the judge withheld some evidence from the jury, while the other will not be told. Later the participants will be asked to recommend a jail sentence. Dr. Marek wants to see if the additional information (knowing that some evidence had been withheld) would affect the recommended sentence. The length of the sentence each participant recommended is presented in years in the chart below.

1)Which is/are being used in this study?

a)one sample is being compared to a population whose mean is known, so a one-samplettest will be used to compare the conditions.

b)two independent samples are being compared, so an independent-samplesttest will be used to compare the conditions

c)two matched samples are being compared, so a dependent-samplesttest will be used to compare the conditions

d)the same participants are experiencing both conditions, so a dependent-samplesttest will be used to compare the conditions

2) State your ALTERNATIVE research hypothesis.This is a TWO-tailed test.

3) State your NULL research hypothesis.This is a TWO-tailed test.

4) The first part of thealternativestatistical hypothesis (H_A) for this experiment (before the comparator) is

a)_{experimental/additional info}

b)_{recommended sentence}

c)_{control/NO additional info}

d)_{recommended sentence}- _{judge's sentence}

e)_{experimental/additional info}- _{control/NO additional info}

5) The comparator in thealternative statisticalhypothesis is

a)?

b)>

c)?

d)

e)=

6) The last symbol in thealternative statisticalhypothesis (H_A) for this experiment is

a)0

b)8

c)10

d)5

7) The comparator in thenull statisticalhypothesis should be
