Question 1 (5 marks) Recall the concept of the sampling error from the first and second weeks of semester. In lectures in Week 6‚ we considered an example in which Optus was estimating the mean telephone expenditure of a household. In the context of that example‚ answer each of the following questions.

or they may even die. This is usually caused by the doctor. For every effect that takes place in the medical technology field‚ there is always a cause. The cause for misdiagnosis was either the diagnostic equipment was defective‚ or since of human error. In rare circumstances‚ gear that is flawed usually causes misdiagnosis since it malfunctions. These breakdowns make it very tough for the patient. A human mistake‚ for the most part‚

The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical‚ spelling) results in a deduction of 5/100. Several opportunities will be offered through the second half of the semester for students to submit a successful report. Sub-par reports may not be resubmitted for regrading
