Difference between Means Test
?2 Goodness of Fit test
?2 Test for Independence
Test for Correlation
Difference betweeen proprtions test (2prop-ztest)

Test for Correlation
Explanation / Answer
Solution:
Here we have to test proportions of each M&M's.
We have to set given hypothesised expected proportions in null hypothesis. Also we have given observed values of browns,yellows,red,blue,orange and greens
Hence we have to use chi square test for goodness of fit to check population proportion.
General hint: Our goal is to use observed sample proportions to test hypotheses about unobserved
population proportions .
Hence correct option is ?2 Goodness of Fit test
