Hypotheses are defined as:

• “Hypotheses are single tentative guesses, good hunches—assumedfor use in devising theory or planning experiments intended to begiven a direct experimental test when possible” (Rogers,1966).
• “Hypothesis is a formal statement that presents the expectedrelationship between an independent and dependent variable”(Cresswell, 1994).
• “Hypothesis is a statement or explanation that is suggested byknowledge or observation but has not, yet, been proved ordisproved” (Macleod & Hockey, 1981).

The null hypothesis represents a theory thathas been put forward, either because it is believed to be true orbecause it is to be used as a basis for argument but has not beenproved. The null hypothesis offers close to null prediction.

The hypothesis actually to be tested is usually given the symbolH0 and is commonly referred to as the null hypothesis. The nullhypothesis is assumed to be true unless there is strong evidence tothe contrary —similar to how a person is assumed to be innocentuntil proven guilty.

The alternative hypothesis is a statement ofwhat a hypothesis test is set up to establish. The otherhypothesis, which is assumed to be true when the null hypothesis isfalse, is referred to as the alternative hypothesis and is oftensymbolized by HA or H1.

• It is opposite the Null Hypothesis.
• It is only reached if H0 is rejected.
• Frequently, the “alternative” is actually the desiredconclusion of the researcher!

For this assignment, select two different business researchscenarios you are interested in testing.

Write a set of hypotheses for each scenario.
