The overdispersion value for the model is (rounded to two decimal places): [value], which indicates that overdispersion [is] an issue and the Possion model assume [lower] variance than the actual response.

In the laboratory, hydrogen gas is usually made by the following reaction: Zn(s) + 2 HCl(aq) → H2(g) + ZnCl2(aq) How many liters of H2 gas, collected over water at an atmospheric pressure of 752 mm Hg and a temperature of 21.0°C, can be made from 1.566 g of Zn and excess HCl? The partial pressure of water vapor is 18.65 mm Hg at 21.0°C.

You are given an m x n grid consisting of ‘0”s and ‘1”s. A ‘1’ represents a single mine in the grid and a ‘0’ represents a single blank tile. A block represents a group of ‘1”s connected horizontally or vertically. Write a function using pseudocode or C++ code that takes as input this 2D grid and returns the number of mines in the largest block. You are allowed to use helper functions. [11 points] Example Input: 0 1 0 1 1 0 0 0 0 1 1 0 0 0 0 1 1 0 1 1 1 1 0 1 1 Example Output: 5 Explanation: The grid has four blocks represented in different colors. The largest block contains 5 mines, so 5 is returned.
