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.

What hormones does my thyroid gland produce? The thyroid gland produces thyroxine (T4), which is a relatively inactive prohormone and lower amounts of the active hormone, triiodothyronine (T3).Collectively, T3 and T4 are referred to as the thyroid hormones.hat does my thyroid gland do? The thyroid gland produces hormones which regulate the bodyâs metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance.
