When the confidence interval of $A$ do not overlap with the mean $B$ then the condition is not verified and $I_{A-B}$ does not contain 0. (True mean difference can then not be 0). As an example, $A = 10, s_A = 5, B = 15, s_B = 7, n_A = n_B = 10$ $I_A = [7.763932, 12.23607]$ $I_B = [11.8695, 18.1305]$ $I_A$ and $I_B$ do overlap but no CI overlap the means $A$ or $B$. $I_{A-B} = [-8.847077, -1.152923]$ So the true value of $A-B$ is lesser than 0, $A$ and $B$ are different. If $B = 13$ then
The thyroid gland also produces another hormone called calcitonin, and the parathyroid glands secrete parathyroid hormone. Parathyroid hormone and calcitonin participate in control of calcium and phosphorus homeostasis and have significant effects on bone physiology.he thyroid gland also produces another hormone called calcitonin, and the parathyroid glands secrete parathyroid hormone.

Calcitonin is released from thyroid gland in response to hypercalemia. On the other hand, parathyroid hormone-as you guessed-is from parathyroid gland in response to low le â¦ vels of blood calcium. Which will cause calcium to be released from bone into blood to compensate.n the other hand, parathyroid hormone-as you guessed-is from parathyroid gland in response to low le â¦ vels of blood calcium.
