Question

anyone know anything about minitab

Answer 1

Two-Sample T-Test and CI: NECW, SSCW

Two-sample T for NECW vs SSCW

N Mean StDev SE Mean
NECW 10 53.4 12.4 3.9
SSCW 10 33.70 4.55 1.4


Difference = mu (NECW) - mu (SSCW)
Estimate for difference: 19.70
95% CI for difference: (10.95, 28.45)
T-Test of difference = 0 (vs not =): T-Value = 4.73 P-Value = 0.000 DF = 18
Both use Pooled StDev = 9.3169


Descriptive Statistics: NECW, SSCW

Variable N N* Mean SE Mean StDev Minimum Q1 Median Q3 Maximum
NECW 10 0 53.40 3.91 12.37 38.00 40.50 58.00 59.75 76.00
SSCW 10 0 33.70 1.44 4.55 27.00 28.75 34.50 38.00 40.00

analyze the data with an independent t-test. Was the hypothesis supported?
