Answer to Question #55615 in Statistics and Probability for Lucy
Question #55615
Paired T-Test and CI: WeightBeginning, WeightEnd
Paired T for WeightBeginning - WeightEnd
N Mean StDev SE Mean
WeightBeginning 20 64.74 5.99 1.34
WeightEnd 20 62.61 6.56 1.47
Difference 20 2.133 2.260 0.505
95% CI for mean difference: (1.075, 3.191)
T-Test of mean difference = 0 (vs ≠ 0): T-Value = 4.22 P-Value = 0.000
Research Question: On average, do adolescent females who take part in the “Get in Shape” programme experience a significant change in their body weights?
