Given the sample mean of GPA, the sample SD, and the SE below:

SM: 3.2454
SD: 0.4635
SE: 0.0309

construct a 68% confidence interval for the population mean gpa

My answer is: 0.4635 to 3.7089

Answered by PsyDAG
68% = mean ± .995 SEm = 3.2454 ± .995(.0309)?

.995(.0309) = .0307455

3.2146545 to 3.2761455

I'm not sure what SD and SE symbolize.
