In a recent study, it is reported that the average time adults spend on a popular social media platform per day is 46 minutes. A researcher would like to verify if this claim is true. He collected data from a sample of 50 adults and found that the average time spent on the social media platform is 43.6 minutes with a standard deviation of 1.8 minutes. (a) Which statistical procedure would you suggest to the researcher to verify the claim? (b) Based on your answer in part (a) and the information given, determine the conclusion that the researcher would arrive at. Use a significance level of $\alpha = 0.05$.

Another fundamental problem in linear algebra is the \"eigenvalue problem\": Given a square matrix A, find an \"eigenvalue\" $\lambda$ (a number) and an \"eigenvector\" $\vec{x}$ that satisfy the equation $A\vec{x} = \lambda\vec{x}$ There is a unique eigenvector $\vec{x}_n$ for every unique eigenvalue $\lambda_n$. An N \times N matrix has at most N unique eigenvalues. We will only be interested in a special class of matrices called \"hermitian matrices.\" The symmetric matrices we have been constructing by adding a matrix to its transpose are hermitian matrices. Write a function that takes a single integer N as its argument and returns an N \times N symmetric random matrix.

1. What is the difference between verification and authentication of an identity? 6. If you're using an identity card as the basis for your authentication scheme, what steps might you add to the process to allow you to move to multi-factor authentication? 7. If you're using an eight-character password that contains only lowercase characters, would increasing the length to ten characters represent any significant increase in strength? Why or why not? 8. Name three reasons why an identity card alone might not make an ideal method of authentication. 10. If you're developing a multi-factor authentication system for an environment where you might find larger-than-average numbers of disabled or injured users, such as a hospital, which authentication factors might you want to use or avoid? Why?
