B5. A transport company claimed that on average a lorry covers at least 100 miles distance in one day. Samples of 50 lorries were taken to prove the observation. The average of the sample is 90 miles with a 2.8 standard deviation. Can we conclude at the 0.05 level, that a lorry covers less than 100 miles of Distance? Use the z test approach to test the above hypothesis.
