1. The point estimate for the difference between the means of the two populations is 2. This means that, on average, the mean of Population 1 is 2 units higher than the mean of Population 2.
2. To find the standard error of the estimate of the difference between the means, we need the sample sizes and standard deviations of both populations. Without this information, it is not possible to calculate the standard error. Please provide the necessary data to proceed.
3. With 19.48 degrees of freedom and a 95% confidence level, we can find the upper limit for the confidence interval using the t-distribution table. However, since the necessary data is not provided, we cannot calculate the upper limit at this time.
4. To determine if Population 1 has a larger mean than Population 2, we need to perform a hypothesis test. Without the necessary data, we cannot calculate the test statistic.
5. Similarly, without the necessary data, it is not possible to calculate the p-value associated with the test statistic.
6. Since we do not have the test statistic or the p-value, we cannot make a conclusion at this time.
Please provide the required data so we can proceed with the calculations.
