Chapter 9: Q. 20 (page 537)

A microbiologist is testing a water sample for E-coli. Suppose the null hypothesis, H0, is: the sample contains E-coli. Which is the error with the greater consequence?

Short Answer

Expert verified

In this case, the error with the greater consequence is the TypeIIerror.

Step by step solution

01

Null hypothesis.

The null hypothesis is beneficial because it's going to be accustomed determine whether or not two measurable events have a relationship.

It can tell the user whether the outcomes are because of chance or are the consequence of controlling a phenomenon.

02

State the error with greater consequence.

"The sample contains E. coli," is the null hypothesis.

So, here's what a kind Ierror looks like:

A microbiologist incorrectly believes the sample has E. coli when it doesn't.

TypeIIerrors are as follows:

A microbiologist believes the sample doesn't contain E. coli when, in reality, it does.

The kind IIerror is the one that has the foremost serious consequences during this scenario.

Suppose that a recent article stated that the mean time spent in jail by a first-time convicted burglar is 2.5years. A study was then done to see if the meantime has increased in the new century. A random sample of 26first-time convicted burglars in a recent year was picked. The mean length of time in jail from the survey was 3years with a standard deviation of 1.8years. Suppose that it is somehow known that the population standard deviation is 1.5. If you were conducting a hypothesis test to determine if the mean length of jail time has increased, what would the null and alternative hypotheses be? The distribution of the population is normal.
