A microbiologist is testing a maor water source of E.coli. Suppose the null hypothesis is that the water source does contain E.coli. The probability that the microbiologist's test concludes that the sample contains E.coli when it actually doesn't, is 0.012. The probability that the microbiologist's test concludes that the sampie doesn't contain E.coli when it actually does, 0.002. a) What is the condence level of the microbiologist's E.coli test?I b) The number of cases that would correspond to Type 2 Errors, if a total of 2000 tests were conducted for the same water source. is c) The number of cases that would correspond to Type 1 Errors. if a total of 3000 tests were conducted for the same water source, is
