2. Two-Sample T-Test and CI: Tomat, Mentimun

Two-sample T for Tomat vs Mentimun

N Mean StDev SE Mean

Tomat 7 772.6 13.6 5.1

Mentimun 7 780.9 10.4 3.9

Difference = mu Tomat - mu Mentimun

Estimate for difference: -8.29

95% CI for difference: (-22.51, 5.94)

T-Test of difference = 0 (vs not =): T-Value = -1.28 P-Value = 0.226 DF = 11

kesimpulan :

Statistik p = 0.226. Nilai statistik P dibandingkan dengan alpha = 0.05. P>alpha, maka

perolehan bromida dalam kedua sayuran tersebut tidak berbeda nyata.
