It is thought that a new process for producing a certain chemical may be cheaper than the currently used process. Eachprocess was run 6 times, and the cost of producing 100 L of the chemical was determined each time. The results, indollars, were as follows:New Process: SI 52 55 53 54 53Old Process: 50 54 59 56 50 58Can you conclude that the mean cost of the new method is less than that of the old method?

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
