Question

According to a researcher who was quoted in a New York Times article in March, 2011, 65 % of U.S. community college students must take at least one remedial course in English, reading, or mathematics.^2 A reporter for the student newspaper at a community college in Florida believes that the percentage of students taking at least one remedial course at her school is higher than CSS. She surveys a random sample of students at her school, asking the students whether they were required to take any remedial courses. Every hypothesis test has a null hypothesis and an alternative hypothesis. The null hypothesis assumes no difference in the population proportion. In this case, it assumes that the proportion of students taking at least one remedial course at the Florida college is the same as the proportion that was reported in the New York Times. Complete the null hypothesis using this assumption. Null Hypothesis: p = _____ The alternative hypothesis is what we try to prove. We try to prove that, somehow, things are different. The reporter believes the proportion at her community college is higher than the proportion that was reported in the New York Times. Remember, the alternative hypothesis claims that the population proportion is either less than (p assumed value). or different from (p notequalto assumed value) a prior value. Give the appropriate alternative hypothesis below. Alternative Hypothesis: p > _______ The reporter finds that in her random sample of 300 students, 201 respond that they were required to take at least one remedial course. What is the sample proportion?

Explanation / Answer

ques 1:

A. p=0.65

B. p>0.65

Ques 2:
