Can someone help me with the rest of the steps, I got the means and standard deviations from the data sets, what comes next?

The production department at Greenside Corporation has devised a new assembly method for one of its lawn tractors. They want to determine if the mean time to assemble the lawn tractor with the new method is different from the mean time to assemble the lawn tractor using the old method. A random sample of 32 assembly times for the new method was collected and a separate random sample of 4G assembly times using the old method was selected (see the le TractorTfmes). Construct a 98% confidence interval for the difference in the two means (unew - uold). Does there appear to be a difference in the means? A; A. -1.248 to -.0649 The condence interval indicates that there is a signicant difference between the mean times for the new and old assembly methods. A B. -1 .744 to 0.432 The confidence interval indicates that there is not a signicant difference between the mean times for the new and old assembly methods. A C. -1.744 to 0.432 The confidence interval indicates that there is a significant difference between the mean times for the new and old assembly methods. A D.-1.248 to -.0649 The condence interval indicates that there is not a significant difference between the mean times for the new and old assembly methods.
