Hello can I get help with these problems please?

1a) Use at-distribution to find a confidence interval for the difference in meansd=1-2using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed usingd=x1-x2.

A95%confidence interval fordusing the paired difference sample resultsxd=1.2,sd=1.9,nd=30.

Give the best estimate ford, the margin of error, and the confidence interval.

Enter the exact answer for the best estimate, and round your answers for the margin of error and the confidence interval to two decimal places.

Best estimate =

Margin of error =

The95%confidence interval is_____ to __________
