4. Let $\phi: \mathbb{Z}[x] \to \mathbb{Z}[i]$ be a map defined by evaluating polynomials at $i = \sqrt{-1}$. Specifically, for $f(x) \in \mathbb{Z}[x]$, define: $\phi(f(x)) = f(i)$, where $\mathbb{Z}[i] = \{a + bi | a, b \in \mathbb{Z}\}$. (a) Prove that $\phi$ is a ring homomorphism. (b) Show that $\phi$ is surjective. (c) Prove that the kernel of $\phi$ is equal to the ideal generated by $x^2 + 1$. (d) Is the kernel of $\phi$ a prime ideal of $\mathbb{Z}[x]$? Justify your answer. Hint for (c): You may need to use the division algorithm. However, $\mathbb{Z}[x]$ is not a Euclidean domain. So how to use the division algorithm?

Please help with assignment The purpose of a study by Gehan et al. was to define the optimum dose of Lignocaine required to reduce pain on injection of propofol. According to these researchers, propofol is a rapidly acting intravenous agent used for induction of anesthesia. Despite its many advantages, pain induced by its injection limits its use. Other studies have shown that intravenous lignocaine given before or with propofol reduced the frequency of pain. Subjects used in the study by Gehan et al. were 310 patients undergoing anesthesia with no lignocaine, while Groups B, C, and D received 1, 2, and 3 mg/kg, respectively, mixed with propofol. The degree of pain experienced by patients was scored from 0 to 3, with patients experiencing no pain receiving a score of 0. The following table shows the patients cross-classified by dose level group and pain score: Group B C Pain score A a Total 242 38 25 5 73 7 5 1 58 7 6 62 8 6 0 0 1 16 8 4 71 310 Total Source: Gehan, P., Karoubi, F., Guinet, A., Leroy, C., Rathat, and J.
