Many grocery stores and large retailers such as Kroger and Walmart have installed self-checkout systems so shoppers can scan their own items and cash out themselves. How do customers like this service and how often do they use it? Listed is the number of customers using the service for a sample of 15 days at a Walmart location. Is it reasonable to conclude that the mean number of customers using the self-checkout system is more than 100 per day? Use the 0.05 significance level. 131 113 95 111 112 85 93 91 138 119 115 133 107 87 144 Click here for the Excel Data File a.

Which of the following are differences between the human and the mice genomes? The mouse genome contains more than 10,000 unique genes that fo not have a counterpart in the human genome. The two species share only a small percentage of their microRNA genes. Only about 10-20% of long noncoding RNA genes are conserved in both species. The human genome has about 20,000 more protein-coding genes.

We have 3 spin 1/2 particles with positive moment $m$, in a configuration. The system is in thermal equilibrium. We have an external magnetic field, $B$ (positive) such that two spin up particles have energy $-mB$ and one has $+mB$. - Note we also have exchange energy $J$ such that the konfiguration (two spin up and one down) energy is $-mB-J$ Show that the partition function is $\frac{-3J}{k_BT} \cdot \cosh\left(\frac{3 \cdot m \cdot B}{k_B \cdot T}\right) + 6 \cdot e^{\frac{J}{k_B \cdot T}} \cdot \cosh\left(\frac{m \cdot B}{k_B \cdot T}\right)$ What is the energy, $U$, of the system?
