Question
5 In a stop watch time study, the actual readings in minutes, recorded for an element are: 0.05, 0.06, 0.05, 0.05, 0.05, 0.06, 0.06, 0.05, 0.06, 0.06, 0.06, 0.06, 0.05, 0.05, 0.06 and 0.05 ) Have sufficient number of readings.been taken for 95% confidence level and ±5% accurancy? (ii) If the rating is 120% what would be the normal time for element?
