Assume that a social worker conducted a research about the effectiveness of independent living skill programs to address the emancipating foster youths aged 21 years old. The program consists of 2 weekly sessions, of which the goal is to improve the independent living skills among the foster youths. To evaluate their program, the social worker selected two groups, 30 foster youths each, out of 187 total foster youths under their caseload. One group ("experimental group") participated in their program to teach the independent living skills for the foster youths; the other group ("control group") did not join in the program. After the 2 sessions, the CPS social worker ran the independent living skill tests to measure the scores from both groups of the foster youths. The scores range from 10 to 100 points, where the higher scores mean the improved independent living skills among the foster youths.

The mean score of the independent living skill tests from the experimental group was 75.6, and the standard deviation is 4.7.The mean score of the independent living skill tests from the control group was 72.3, and the standard deviation is 8.8. The CPS social worker claims this result as a success of their 2-session program, because the mean independent living skill score of the experimental group students is higher than the mean independent living skill score of the control group.

State the non-directional research hypothesis and the null hypothesis. Make sure to include 1) DV, 2) IV, and 3) relationship in a complete sentence for BOTH hypotheses. (3 points)

State the directional research hypothesis supporting the social worker's claim, and the null hypothesis. Make sure to include 1) DV, 2) IV, and 3) relationship in a complete sentence for BOTH hypotheses. (3 points)

The social worker performed the inferential statistical test, which produced the p-value of 0.075. Rejection level is set to p=0.05.Explain what this p-value of 0.075 means in terms of sampling error, true relationship, and testing null hypothesis (reject or fail to reject).Note that these three underlined terms should be included in your answer.
