Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

Weights of Vacuum Cleaners Upright vacuum cleaners have either a hard
body type or a soft body type. Shown are the weights in pounds of a sample of
each type. At a=0.10, can it be concluded that the means of the weights are
