Suggest one possible source of systematic error in the investigation.

Discuss systematic errors in all experimental work, their impact on the results and how they can be reduced.

Which statement about systematic errors is not correct?A A systematic error can be caused by using an incorrectly calibrated instrument.B One particular type of systematic error can affect all the measurements by the same amount.C The effect of a systematic error can be reduced by repeating and averaging themeasurements.D Zero error is a type of systematic error

Systematic error and zero error are examples of environmental errors.a.Falseb.True

can you write an ending statement The results found in this investigation can be said to be accurate and reliable because the data does not have any anomalous results and the standard deviation and the standard errors were relatively low when the mean value of different nuts are compared. The error bars were relatively short and some of them were overlapping; but that might be a cause of errors during data collection and random errors during the experiment.

Suppose that at the end of the five-year study described above, a greater proportion of the hormone-treated group have breast cancer and heart disease. This observed difference is statistically significant. Researchers are so alarmed by the results that the experiment is ended early to prevent further harm to the health of the women participating in the hormone group. Since the null hypothesis was rejected, it is possible researchers made a type I error.Given the type of error made in this situation, what could researchers do to reduce the risk of this error?
