Hi! I am having trouble understanding how to construct confidence intervals for these problems. Your help is greatly appreciated.

Read the following scenario and complete each of the problems below: A new car manufacturing company has emerged and has claimed that its new hybrid car, the Pushc, gets a better gas mileage than the highest ranked Toyota Prius. Consumer Reports Magazine decides to test this claim at a 5% level of significance. Consumer Reports randomly selects 10 of each type of car, calculates the miles per gallon for each car in the study, and records the data in the table below. Assume miles per gallon of the cars is normally distributed. Pusho 54.1| 52.4 55.7 49.7 50.6 43.9 51.3 54.5l 56.9 49.9 Prius 53.2 54.3 49.8 50.1 50.5 56.1 47.3 53.4 56.8 46.7 A. Construct a 90% condence interval for the difference in the gas mileage of Pushc and Prius. B. Construct a 95% condence interval for the difference in the gas mileage of Pushc and Prius. 0. Write a statement comparing and contrasting the two confidence intervals and the significance of having 0 in both of those intervals
