You use a chi-square test for goodness of fit to see how well the sample of adolescent girls with anorexia nervosa fits the census data. What is the most appropriate null hypothesis? The distribution of where the adolescent girls live is equal across the four geographic regions. The distribution of where the adolescent girls live is not equal across the four geographic regions. The distribution of where the adolescent girls live is different from that provided by the census data. The distribution of where the adolescent girls live is the same as that provided by the census data. 2. Fill in the missing values in the following table indicating the expected frequencies in each category for a sample size

Question
I need help. How do I find the two missing
Suppose you are reading a study conducted in the year 2000 about adolescent girls with anorexia nervosa in the United States. The authors report the following frequency data on regions where the 522 adolescent girls with anorexia nervosa in their random sample reside:
Observed Frequencies
Region
|
|||
---|---|---|---|
West
|
South
|
Midwest
|
Northeast
|
110 | 206 | 110 | 96 |
You wonder whether the differences in the frequencies are due to the disease being more prevalent in certain areas of the country, whether the study simply included more girls from certain regions, or whether the distribution matches the geographic distribution of the US population. You obtain the following data from the 2000 census:
Percent Distribution of the US Population by Region
Region

|||
---|---|---|---|
West
|
South
|
Midwest
|
Northeast
|
22.46% | 35.62% | 22.88% | 19.04% |

1. You use a chi-square test for goodness of fit to see how well the sample of adolescent girls with anorexia nervosa fits the census data. What is the most appropriate null hypothesis?
The distribution of where the adolescent girls live is equal across the four geographic regions.
The distribution of where the adolescent girls live is not equal across the four geographic regions.
The distribution of where the adolescent girls live is different from that provided by the census data.
The distribution of where the adolescent girls live is the same as that provided by the census data.
2. Fill in the missing values in the following table indicating the expected frequencies in each category for a sample size of 522, if the null hypothesis is true:
