1. Find the test statistic 

 

2. Identify the P-Value 

A college entrance exam company determined that a score of 25 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve
this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 200 students who completed this core set of
courses results in a mean math score of 25.6 on the college entrance exam with a standard deviation of 3.6. Do these results suggest that students who complete the core curriculum
are ready for college-level mathematics? That is, are they scoring above 25 on the math portion of the exam? Complete parts a) through d) below.
The appropriate null and alternative hypotheses are Ho
25 versus H₁: P
b) Verify that the requirements to perform the test using the t-distribution are satisfied. Check all that apply.

A. The sample size is larger than 30.
