Create a vector using the values 145, 122, 127, 245, 362, 152 and store it in a variable called starting_weights. Create a second vector using the values 125, 128, 117, 205, 300, 173 and store it in a variable called ending_weights. Now subtract starting_weight from ending_weight and store it as a variable called weight_loss. Next, determine the total weight loss. Finally, determine the mean weight loss
