No use of pencil.Kindly write your answer on the answer sheet provided on page 3.A. Two types of rice verities are being considered for yield and a comparison isneeded. Thirty hectares were planted with rice varieties exposed to fairlyuniform growing conditions. The results are:Variety A80 sacks/ha5.9Average YieldSample varianceAt 0.05 level of significance, can we conclude that variety A is the better type?1. What is the resulting degrees of freedom (df)?Solution:2. What is the True Value (TV)?3. What is the resulting computed value (CV)?Given:Variety B35 sacks/ha12.1Solution: B. Suppose the National Transportation Safety Board (NTSB) wantsto examine the safety of compact cars, midsize cars, and full-sizecars. It collects a sample of three for each of the treatments (carstypes).
