The mayor of Lawrenceville indicated in a news interview that the percentage of students at GGC studying business is at least 30%. For your marketing project, you intend to test this claim. The correct setup of a hypothesis test for this situation is:a) H0: p < .30 Ha: p ≥ .30b) H0: p ≤ .30 Ha: p > .30c) H0: p ≥ .30 Ha: p < .30d) H0: p > .30 Ha: p ≤ .30

c)  

Explanation:

Null hypothesis contains  ≤,≥ ,= signs

Alternative hypotheses contains < , > , ≠ signs.

Let p be the percentage of students at GGC studying business.

Given: The mayor of Lawrenceville indicated in a news interview that the percentage of students at GGC studying business is at least 30%.

i.e. p ≥ 0.30  [30%=0.30 in decimal]

So, Null hypothesis

Then, the alternative hypothesis would be ( opposite of the null hypothesis)

i.e.

hence, the correct answer is c)   .
