# Single mean, one-tailed; single populations proportion, two-tailed

Need a brief example of the following:

Cite an example of how you could/would apply a test of a hypothesis for a single mean, one tail test described in the lecture to real world situations? Make sure you state your hypothesis in both the null and alternate form as well as showing the hypotheses in symbol form such as Ho : u = 15 where u ( lower case U on your keyboard ) stands for the population mean. You do not need to complete the entire five step process using actual numbers.

Cite an example of how you could/would apply a test of a hypothesis for a single population proportion, two tail test described in the lecture to real world situations? Make sure you state your hypothesis in both the null and alternate form as well as showing the hypotheses in symbol form .You do not need to complete the entire five step process using actual numbers.

#### Solution Preview

Here is a situation where we cause hypothesis testing at work. Imagine my company manufactures products. There is a high rate of errors in the manufacturing process, which is costing the company a lot of money. Management was wondering if implementing a new program, in which employees receive 4 extra hours of training, would reduce the number of errors that they make will decrease significantly, which would save the company money.

We could set up an experiment, with a hypothesis test.

What he would do is randomly assign xx employees to receive extra training, while xx employees ...

#### Solution Summary

The Single mean, one-tailed; single populations proportion and two-tailed are examined.
