and 9: t-test t test problem with d=0,05 The weight of metal plate is investigated. The average weight from 4 sample is == 11.5 kg and the standard deviation (s) is 0.5kg. Hypothesis test is : (Ho: Mo Mo= 12 kg Hi. a) Find the Pualue for X-11.5kg, and test the null hypothesis, Ho, it to can be accepted. b) Find the type I error (B) when the true mean weight is Mislliasky and the type I error() is d.os. c) Find the required sample size n to detect the true mean weight i. assume =0.1 you may use oc curves to solve b) and c) * 1.00 0.90 0.80 0.70 0.60 0.50 SA Probability of not rejecting Ho 0.40 0.30 0.20 0.10
