In 2006, a sample of 400 students whose family's an income was between $70,000 and $80,000 had an average verbal SAT score The point estimateof the mean for this group is and the 80% confiden interval for this group is a. 500; (493.55, 506.45) b. 500; (504 55, 517.45) c. 511: (493.55, 506.45) d. 511: (504.55, 517.45Explanation / Answer
Dear student,
According to Chegg guidelines only the first four questions are answered.
A, Here, we fail to reject the null hypothesis with a sample of n=22. Since here the p value is greater than 0.05.
B, the range of raw values in 80 percent confidence interval will be smaller than that of 95 percent confidence interval. And the precision will be lower than that of 95 percent confidence interval values.
C, Increasing sample size will increase the possibility of committing type 2 error.
D, A measure of absolute magnitude of the effect on a research is called coefficient of determination.
