I would like to under what specific features of a hypothesis do each of the criteria adequacy- testability, fruitfulness, scope, simplicity, and conservatism try to measure?

The criteria that you mention do not measure anything. They are more general aspects of any research proposal. They are parameters in wording and communicating a working hypothesis.
All of these are also controversial.

Consider a hypothesis:
Human beings living in capitalist countries are more egocentric than those who do not.

The hypothesis is that egocentrism is a function of the sort of society in which one is born and raised. The cause is the society, the effect is egocentrism (or its opposite). There is a cause and an effect. The cause must adequately explain the effect.

A hypothesis is, by definition, testable. What this means remains controversial. In the most genera sense, there must be an acceptable way to show, suggest or "prove" that your dependent variable ...

Solution Summary

The features of a hypothesis are provided. Criteria adequacy is examined.

Hypothesis Tests and Test Statistic

1. (1 point) The Dick Tracy Co. has developed micro-miniaturized circuitry that will enable them to produce a wristwatch-sized video-telecommunicator. Research and development costs are believed to be high, and the company is uncertain whether it should proceed. The company has a strategic alliance with Cells-R-Us, a national provider of cellular telephone services, so a moderate-to-large sample of current cell phone customers is possible. The Marketing Department of the Dick Tracy Co. has developed a survey, which contains a list of possible features of next-generation telecommunicators, including compactness, ease of use, internet access, audio downloading/playing, video image downloading/video imaging, voice messaging, text messaging, et al. Survey respondents will be asked to rank order these features, first on the basis of personal preference, and then on the basis of willingness to pay a premium for them. From the perspective of the Dick Tracy Co., what are a null and an alternative hypothesis based on the perceived results of the survey?

2. (4 points) A TV manufacturer purchases picture tubes from independent suppliers, and contractually requires that the tubes have an average life of at least 550 hours. The firm received a shipment of tubes from a supplier, tested 25 tubes, and found that the average tube life was 535 hours with a sample standard deviation s = 37 hours.

1. What is the appropriate hypothesis test to determine if the shipment should be accepted or rejected? State the hypotheses.
2. What is the test statistic? Compute its value.
3. What is the critical value if the hypothesis test is conducted at the 5% level of significance? How does the computed value of the test statistic (from b.) compare with the critical value? Show on a sketch.
4. Should the shipment be accepted or rejected? Why?
