Test the claim that the proportion of men who own cats is significantly different than 60% at the 0.05 significance level. The null and alternative hypothesis would be: H0:μ=0.6 H1:μ<0.6 H0:p=0.6 H1:p≠0.6 H0:p=0.6 H1:p>0.6 H0:p=0.6 H1:p<0.6 H0:μ=0.6 H1:μ>0.6 H0:μ=0.6 H1:μ≠0.6 The test is: right-tailed two-tailed left-tailed Based on a sample of 50 people, 52% owned cats The test statistic is:(to 4 decimals) The positive critical value is:(to 4 decimals) Based on this we: Fail to reject the null hypothesis Reject the null hypothesis

The selectivity coefficient, KK+,H+, for a K+ ion-selective electrode is 0.00539. When the electrode is placed into a 1.48 × 10-5 M K+ solution at pH 6.60, the potential is -0.154 V vs. SCE. If the pH of the solution is lowered to 1.21 and the ionic strength is kept constant, what is the potential of the electrode? Assume ẞ = 1 for the electrode.

(1 point) Compute the Laplace transform. Your answer should be a function of the variable s: $\mathcal{L}\left\{5 + u_{7/2}(t)e^{-t}cos(\pi t)\right\} =$ You may find the following formulas useful: $\cos(bt + \pi) = -\cos(bt)$ $\sin(bt + \pi) = -\sin(bt)$ $\cos(bt + \frac{\pi}{2}) = -\sin(bt)$ $\sin(bt + \frac{\pi}{2}) = \cos(bt)$ If you don't get this in 2 tries, you can get a hint. Hint: • Remember that $\mathcal{L}\left\{k\right\} = \frac{k}{s}$ • For the $u_{7/2}(t)e^{-t}\cos(\pi t)$ term, it is probably easiest to first pull $e^{-t}$ out of $\mathcal{L}$. • When $u_{7/2}(t)$ comes out of $\mathcal{L}$, it changes $\cos(\pi t)$ to be $\cos(\pi(t + 3.5)) = \cos(\pi t + 3.5\pi)$ which simplifies to $-(\sin(\pi t))$.
