An EWMA chart is used to monitor a temperature in a pharmaceutical process. An automated measurement is obtained selected every minute and added to the EWMA chart. Experience indicates that s = 0.5 °F. The process target (process mean when in control) is 72 °F. The EWMA uses a lamda value 2=0.35. If the accumulated value of the EWMA at the end of measurement 47 is Z47 = 72.165 and measurement 48 is equal to X48 = 72.466, what will be the accumulated value of the EWMA at the end of measurement 48, that is Z48 = ? O 72.225 O 72.240 72.285 72.270 not enough information O 72.255
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
