t-value (to 4 decimals) Degrees of freedom 25 p-value (to 4 decimals) d. Compute the t-value, degrees of freedom, and p-value for the hypothesis test. What is the point estimate of the difference between the means for the two populations? 69 points higher if parents are college grads.
u2 = population mean math score parents high school grads.
µ1 = population mean math score parents college grads. Formulate the hypotheses that can be used to determine whether the sample data support the hypothesis that students show a higher population mean math score on the SAT if their parents attained a higher level of education. Use the Excel Online spreadsheet below to answer the following questions. The second sample shows the SAT math test scores for students whose parents are high school graduates but do not have a college degree. The first sample shows the SAT math test scores for students whose parents are college graduates with a bachelor's degree. Two samples are contained in the Excel Online file below. SAT math scores for independent samples of students follow. A research hypothesis was that students whose parents had attained a higher level of education would on average score higher on the SAT.
