1) The critical value of a normal distribution when the alternate hypothesis shows to be greater than the expected mean and the type 1 error is 5% should be:

2)The project manager of a company developed an improvement alternative where the results showed a productivity increase. The plant manager is not confident with this information and wants to validate the improvement with a 97.5% of confidence level. The expected mean is 20lbs/hr and has a variance of 4lbs/hr. The plant manager requested 10 samples: 20.3, 23, 22, 23.5, 21.9, 24, 23, 22, 22.5, 24. Develop the five steps of the hypothesis analysis and determine if the project manager improved the rate from 20lb/hr.

The hypotheses are:

	Ho: = 20lb/hr, H1: < 20lb/hr
	Ho: = 20lb/hr, H1: > 20lb/hr
	Ho: = 20lb/hr, H1: 20lb/hr
	Ho: < 20lb/hr, H1: > 20lb/hr

The probability distribution is:

	Normal Distribution
	Student T Distribution
	Chi-Square Distribution
	F Distribution

4)The project manager of a company developed an improvement alternative where the results showed a productivity increase. The plant manager is not confident with this information and wants to validate the improvement with a 97.5% of confidence level. The expected mean is 20lbs/hr and has a variance of 4lbs/hr.

Develop the five steps of the hypothesis analysis and determine if the project manager improved the rate from 20lb/hr.

The experimental value:

5)The project manager of a company developed an improvement alternative where the results showed a productivity increase. The plant manager is not confident with this information and wants to validate the improvement with a 97.5% of confidence level. The expected mean is 20lbs/hr and has a variance of 4lbs/hr. The plant manager requested 10 samples: 20.3, 23, 22, 23.5, 21.9, 24, 23, 22, 22.5, 24. Develop the five steps of the hypothesis analysis and determine if the project manager improved the rate from 20lb/hr.

The conclusion is:

	Ho is accepted, or H1 is rejected
	Ho is accepted, or H1 is accepted.
	Ho is rejected, or H1 is rejected.
	Ho is rejected, or H1 is accepted.

6)The dispenser of a liquid medicine is dispensing 2ml/hr according to the doctors instructions. The nurse wants to be sure that the dispenser is working accordingly. With a 90% of confidence level, determine if the equipment is accurate. Samples: 2.1, 1.8, 2.1, 2, 1.9, 2.2, 2.1, 2, 1.8, 1.9. Develop the five steps of the hypothesis analysis and determine if the is working as requested.

The conclusion is:

	Ho is accepted, or H1 is rejected
	Ho is accepted, or H1 is accepted
	Ho is rejected, or H1 is rejected
	Ho is rejected, or H1 is accepted
