3) Researchers are testing a new program for children who are learning to read. Each child is randomly assigned to either the treatment group or a control group, and reading ability is measured using a variable that is appropriately analyzed as continuous. All assumptions of the t-test are met.

But alas - I spilled my wine over the t-statistic and was so preoccupied with the mess that I forgot to provide the Pvalue to supplement the analysis.

a) What statistical test was conducted? Is there a statistically significant difference between the groups? Can you calculate and comment on the magnitude of the t-statistic? What is the null hypothesis for this research question and what will you do with it?

Summarize the research in no more than three sentences and include a proper interpretation of the 95% confidence interval.
