A researcher thinks that white bread consumption increases blood sugar. Sugar in the blood It is known that the mean of the values with normal distribution is 15 with 100 standard deviation. Whole wheat The average blood sugar value of 30 people who consumed regular white bread instead of bread was 140. Test whether white bread increases blood sugar levels or not with 99% confidence.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
