A food company is planning to market a new type of frozen yogurt.  However, before marketing this yogurt, the company wants to find what percentage of people like it.  The company's management has decided that it will market this yogurt only if at least 35% of the people like it.  The company's research department selected a random sample of 400 people and asked them to taste this yogurt.  Of these 400 people, 112 said they liked it.  If we were to perform a significance test, what is the value of the test statistic for this test?
