please can you check this I think I have missed something not sure of the Df is 9 or 18 and so it would change the answer

Part A

A career developmental researcher facilitated a study to assess 'career readiness' among young people. The researcher recruited 20 participants and randomly allocated 10 participants in Condition 1 who received 12 weeks of employability skills training intervention and 10 participants to Condition 2 who did not receive the intervention. A two-tailed, Related Samplest-test witha= .05was used to test whether participants in Condition 1 scored significantly differently on Career Readiness to those in Condition 2. The statistical hypotheses,H0:?_D= 0, H1:?_D0.

The average score for participantsin Condition 1 wasM= 26.30 (SD= 7.48), the average score forparticipants in Condition 2wasM= 19.40 (SD= 5.76). The mean difference wasMD= 6.90 (SD=9.75). Thet-obtained (does not fall into the region of rejection, therefore we retain the Null hypothesis. The results of the Related-Samplest-test do not show a significant difference on career readiness scores with and without the employability skills training intervention,t(9) = 2.24,p= 0.052, 95% CI [-.07, 13.87].

Cohen's cut-offs for effect sizes were applied (Cohen, 1998),d= .708 representing the point estimate used in estimating a large effect size. The Related-Samplest-test was performed using SPSS27 determining that participants in Condition 1, who received the employability skills training intervention did not scoresignificantly differenton career readiness compared to participants Condition 2 who did not receive the intervention.

A career developmental researcher is interested in how young people can optimise their career development so they feel well prepared and ready for their future career. The researcher thinks that a programme tailored to build employability skills (e.g., communication, adaptability, problem solving, emotional intelligence, and teamwork to name a few), could be helpil for young people to feel career ready. The researcher recruits 20 participants and randomly allocates 10 participants to Condition 1 and 10 participants to Condition 2. The participants in Condition 1 receive 12 weeks of employability skills training intervention. The participants in Condition 2 do not receive the intervention (i.e., they are in the control condition). The researcher then asks all participants to complete a measure of career readiness because the researcher wants to test whether the participants in Condition I scored significantly dierently on career readiness to those in Condition 2.
