Answer question (c) 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 150 students who completed this core set of courses results in a mean math score of 25.4 on the college entrance exam with a...

Acredit score is used by Credil agencies (such as mortgage companies and banks) to assess the creditworthiness of individuals. Values range from 300 to 850, with a credit score over 700 considered to be a quality credit risk. According to a survey, the mean credit score is 7075. A credit analyst wondered whether high-income individuals (incomes in excess of S100.000 per year) had higher credit scores. He obtained a random sample of 38 high income individuals and found the sample...

Researchers wanted to determine if the psychological profile of healthy children was different than for children suffering from recurrent abdominal pain (RAP) or recurring headaches. A total of 210 children and adolescents were studied and their psychological profiles were graded according to a child behavior checklist. Children were stratified in two age groups: 4 to 11 years and 12 to 18 years. The results of the study are summarized in the accompanying table. Complete parts (a) through (f) below. B...
