1. To test the series ∞∑k=1 1/5√k^3 for convergence, you can use the P-test. (You could also use the Integral Test, as is the case with all series of this type.) According to the P-test: ∞∑k=1 1/5√k^3 converges the P-test does not apply to ∞∑k=1 1/5√k^3 ∞∑k=1 1/5√k^3 diverges Now compute s4, the partial sum consisting of the first 4 terms of ∞∑k=1 1 /5√k^3: s4= 2. Test the series below for convergence using the Ratio Test. ∞∑n=1 n^5 /1.2^n...

You wish to test the following claim (Ha) at a significance level of α=0.001       Ho:μ1=μ2       Ha:μ1≠μ2 You believe both populations are normally distributed, but you do not know the standard deviations for either. Use non-pooled test. You obtain a sample of size n1=17 with a mean of M1=51.4 and a standard deviation of SD1=16.2 from the first population. You obtain a sample of size n2=23 with a mean of M2=65.4 and a standard deviation of SD2=18.4 from the second population....

Learning Goal: To understand reaction order and rate constants. For the general equation aA+bB?cC+dD, the rate law is expressed as follows: rate=k[A]m[B]n where m and n indicate the order of the reaction with respect to each reactant and must be determined experimentally and k is the rate constant, which is specific to each reaction. Order For a particular reaction, aA+bB+cC?dD, the rate law was experimentally determined to be rate=k[A]0[B]1[C]2=k[B][C]2 This equation is zero order with respect to A. Therefore, changing...
