If the null hypothesis specifies that men and women are equally likely to attend graduate school, then among a random sample of 200 graduate students, the expected frequency of women equals
a) 50% b) 50 c) 100 d) 200
The value of chi-square never can be
a) less than zero. b) zero. c) less than one. d) more than one hundred.
The null hypothesis is false if two or more population proportions differ
a) from each other.
b) appreciably from each other.
c) from the corresponding hypothesized proportions.
d) appreciably from the corresponding hypothesized proportions.
Explanation / Answer
expected frequency of women equals =np=200*0.5=100 option C
value of chi-square never can be a) less than zero.
The null hypothesis is false if two or more population proportions differ d) appreciably from the corresponding hypothesized proportions.
