Transcribed Image Text:In Fragile Families and Child Wellbeing study, a researcher wants to evaluate whether primary caregiver relationship
to youth and how much time youth lives with primary caregiver coupled with household income would affect number
of days youth absent from school. The following variables are considered: zizaloqui a obnos of enslq sodrum od

- a. Use a = 0.10 to test for a statistically significantly difference between the population means for first- and fourth-round scores. What is the p-value? t-value (to 3 decimals) Degrees of freedom p-value is greater than 0.20 What is your conclusion? There is no significant difference between the mean scores for the first and final rounds. b. What is the point estimate of the difference between the two population means? (to 2 decimals) For which round is the population mean score lower? First round c. What is the margin of error for a 90% confidence interval estimate for the difference between the population means? (to 3 decimals) Could this confidence interval have been used to test the hypothesis in part (a)? Yes Explain. Use the point of the difference between the two population means and add and subtract this MOE. If zero is in the interval the difference is not statistically significant. If zero is not in the interval the difference is statistically significant.arrow_forwardA researcher is studying psychological factors in athletic achievement among teenage boys.
