(b) The study described here examined the accuracy of 10 different fitness tools (wearable devices and apps) in the same manner. What would be a major issue with running 10 different $ t $ tests to examine their accuracy?There is no major issue with running a set of ten tests with the same objective of determining the accuracy of each tool.With a single hypothesis test, the chance of wrongly rejecting the null hypothesis is the significance level $ \alpha $. With a set of ten tests with the same objective, the probability of at least one test wrongly rejecting $ H_{0} $ will be notably greater than the significance level.With a single hypothesis test, the chance of wrongly rejecting the null hypothesis is determined by the standard error mean. With a set of ten tests with the same objective, the probability of at least one test wrongly rejecting $ H_{0} $ will be notably greater since there will be greater chance for more errors.With a set of ten tests, a lot of calculations need to be done and the chance of making at least one calculation error will'be notably greater.

Gradient, Divergence, Curl, Divergence Theorem, Stokes's Theorem Divergence Theorem & Stokes's Theorem 1. Verify the divergence theorem for the following vector field $\vec{D} = 3\rho \hat{a}_\rho - 2z\hat{a}_z$ between the region of a cylindrical surface defined by $0 \le \rho \le 2$ extending from $0 \le z \le$ 5. Recall the Divergence Theorem: $\oint_S \vec{D} \cdot d\vec{s} = \iiint_V (\nabla \cdot \vec{D})dv$
