1. Find the P-value for a right-tailed test about a mean with n = 30 and test statistic t = 46.9516

2. Find the P-value for a two-tailed test about a population mean of 49.1 with n = 83, sample standard deviation of 3.35, sample mean of 45.21 and 95% confidence level.

3. With sample size of 100, sample mean of 49.4,standard deviation of 4.1 and confidence level of 95%, the Confidence Interval is?
