Part 3 Minitab printouts 1 OneSample T Dry weight of cork 5

Part 3: Minitab printouts 1. One-Sample T: Dry weight of cork (5 points) Test of 3.275

Solution

a) p value = 0.459

p > 0.05 Hence accept null hypothesis.

There is no statistical evidence to claim that mean is less than 3.275

--------------------------------------

2) p value =0.089

p value lies between 0.05 and 0.10

Hence accept null at 5% significance level but reject at 10% sign. level

3) Confidence interval gives the range of values within which the sample mean falls as sample size becomes large.
