From extensive testing, the mean drying time of a company’s spray paint product is thought to be normally distributed with mean μ = 100 seconds and standard deviation of σ = 4 seconds. The manager of the research division of the company that produces the paint considers using a different colorant and wants to know whether the mean drying time will change. f the managers choose to use a significance level of α = 0.10 and assume σ = 4, identify the power of a Z test to detect a mean increase of 2 seconds (μa = 102). They plan to look at a sample of 25 drying times and do a right-tailed hypothesis test. Also identify the probability of making a type 2 error if the true mean drying time with the new colorant is 102 seconds, μa = 102

Under some conditions ammonia can break down into its component gases: 2 NH3 (g) → N2 (g) + 3 H2 (g) A container starts out with 4.27 moles of ammonia. The ammonia breaks down completely and the resultant gas mixture of nitrogen and hydrogen has a total pressure of 167 kPa. What is the partial pressure of the hydrogen in the mixture of gases. (Assume there are no other gases present)

If the velocity distribution of a fluid flowing through a pipe is known, the flow rate Q (that is, the volume of water passing through the pipe per unit time) can be computed by $Q = \int vdA$ where $v$ is the velocity and $A$ is the pipe's cross-sectional area. (To grasp the meaning of this relationship physically, recall the close connection between summation and integration.) For a circular pipe, $A = \pi r^2$ and $dA = 2\pi rdr$. Therefore, $Q = \int_0^{r_0} v(2\pi r)dr$ where $r$ is the radial distance measured outward from the center of the pipe. If the velocity distribution is given by $v = 2(1 - \frac{r}{r_0})^{1/6}$ where $r_0$ is the total radius (in this case, 3 cm), compute Q using an appropriate built- in function of MATLAB.
