Choose the t test (which mean pick ONE) you think is appropriate out of the three t tests listed below to determine the t-value for the data (you can copy the results from your SPSS output and past them here:
1. One sample (Mean) test
2. Two samples (independent t-test) test
3. Paired/related sample t tests
From the t test you ran above, tell me the confidence intervals (look under 95% CI, lower and upper) for the data and interpret what they mean.

Expert Solution

here we will use paired sample t test because the Quality of Marriage and Quality of the Parent–Child Relationship independent of each other from SPSS we have

Paired Samples Statistics
Mean   N   Std. Deviation   Std. Error Mean
Pair 1   marriage   78.5333   30   12.52785   2.28726
Relation   41.2667   30   11.16933   2.03923

Paired Samples Test
       Paired Differences
Mean   Std. Deviation   Std. Error Mean   95%CI of the Difference   t   df   Sig. (2-tailed)
Lower   Upper

marriage - Relation 37.26667 12.62164 2.30439 32.55367 41.97966 16.172 29 .000

the 95 % confidence interval is (32.55367 ,41.97966 ) it tells us that we are 95 % sure / confident that the differnece of population mean of the variables give lies in this interval .
