Assume you want to do a project that compares the survey results

Assume you want to do a project that compares the survey results before an intervention to those after an intervention in the same sample (the same people will take both surveys). You plan to use a paired t-test to analyze your results. Using the “Determining the Appropriate Sample Size,” Topic Material, perform a sample size calculation to determine how large your sample should be. Justify your sample size calculation with citations. Discuss how your sample size may affect the validity of your study. I plan to use Qauntitative descrptive design. 1 page, APA. My topic is on  “the use of Advanced Practice Providers in triage in improving waiting times in Emergency departments”.  https://www.ibm.com/support/knowledgecenter/SSCVKV_9.1.1/Campaign/CampaignProcesses/To_use_the_sample_size_calculator.html.
