B. Solve the following problems.1. A researcher wants to eatimate the average number of children with congenitalheart disease who are between the nges of 1-5 years old. How many children ahouldbe enrolled in this study, if the researcher plans on uning a 95% confidence level andwants a margin of error of O.5 and standard deviation 4?2. Allan, a Grade 12 senior high school student, wants to estimate the averagenumber of students who will pursue collage degree in a certain school. How manysample sizes does he need, iff he plana to use 98% confidence, 0.5 as the margin ofCIror, and a standard devintion of 5.C. Find other methods of determining sample size, then compare these with theformula proposed in this module. If you are to select a method, which will it be?Explain your idea.
