The tensile strength of apot welds produced by a robot welder is normully distributed, with a mean of R10000.00 per square meter and standard deviation of R800.00 per square meter. For a simple random sample of 4 welds, the probnbility that a sample mean will be at least R10299.00 per square meter is Select one: 0.3085. 0.6915 0.5, 0.0308. 0.9332
