The college theater department recently staged a production of a modern musical. A researcher recorded the gender of each student entering the theater and found a total of 37 females and 18 males. Is the gender distribution for theater goers significantly different from the distribution for the general college? Test at the.05 level of significance.

Ans:
Chi square critical=CHIINV(0.05,1)=3.841
Chi square calculated=1.21
As,calculated chi square<critical chi square,
Fail to reject null hypothesis,distribution of gender for theaters goers is not significantly different from the gender distribution.(last option is correct)
critical chi square=3.841
Calculate chi square=20.12
As,calculated chi square score>critical chi score,
Reject null hypothesis,distribution of gender for basketball fans is significantly different from the gender distribution.(second option is correct)
