please help with 1 and 2

2) The number of girls in 400 families with 3 children is investigated. There are 58 families with no girl, 137 with one girl, 171 with two girls and 34 with three girls. We would like to use a 0.01 significance level to test the claim that the number of girls in a 3-children family follows the binomial distribution (shown in question number 1). That is the ratio is 1:3:3:1. Instruction: 1) Must contains 4 steps as shown on the instructor's video. 2) Must identify whether the null hypothesis or the alternative hypothesis is the claim. 3) Create a similar table (the table must contain observed, expected, O-E, (0-E)^2,(0-E)^2/E) 4) Instead of finding the p-value, find the test statistic and two critical values. 5) When drawing conclusion, must follow the wording from the textbook. 6) If your answer does not follow the instructions above, you will get no credit. 1) Create a probability distribution for the number of girls in a family of 3 children by answering the following questions: a) List all possible outcomes as the sample space. b) Use either the sample space from part a or use your TI 84 to calculate the following (If you are using the sample space, write your answer as a fraction; if you are using TI 84, write the command on the screen of your calculator and then write your answer as decimals): P(x = 0) = P(x = 1) = P(x = 2) = P(x = 3) = c) Complete the distribution table below: Number of Girls (x) Probability P(x)
