I am having trouble with this question chi square 1-3

1) In an experiment in breeding mice, a geneticist has obtained 120 brown mice with pink eyes, 48 brown mice with brown eyes, 36 white mice with pink eyes and 13 white mice with brown eyes. Theory predicts that these types of mice should be obtained in the ratios 9 : 3 : 3 : 1. Please construct the observed table and the expected table. 2) A new container design has been adopted by a manufacturer, and the company wishes to know if the color of the container matters. Color preferences indicated in a sample of 150 individuals are as follows: Color Red Blue Green Number choosing 40 64 46 Test, using alpha equal to 0.10, to see if the color preferences are the same. Please construct the observed table and the expected table. (M observed table has been 3M1) 3) Professor X claims that he grades on a curve that is, 10% of students receive A's, 20% B's, 40% CS 20% D's and 10% F's. [This is the classic \"grading on a curve\" assumes a normal distribution of "success\" & puts C at the mean.] A student who doubts this collects a sample of 63 grades from Frump's classes and nds 8 A's, 7 3'5, 28 CS, 11 D's and 9 F's. does this indicate that Prof. X's grades are not distributed as he claims? Please construct the observed table and the expected table
