Suppose you are reading a study conducted in the year 2000 about left-handed people in the United States. The authors report the following
frequency data on the age of the 456 lefties in their random sample:

You wonder if the age distribution of left-handed people matches the age distribution of the US population. You obtain the following data from the
2000 census:

You use a chi-square test for goodness of fit to see how well the sample of left-handed people fits the census data. What is the most appropriate
null hypothesis?
O The distribution of ages among left-handed people is equal across the five age categories.
O The distribution of ages among left-handed people is the same as that provided by the census data.
O The distribution of ages among left-handed people is different from that provided by the census data.
The distribution of ages among left-handed people is not equal across the five age categories.

Fill in the missing values in the following table indicating the expected frequencies in each category for a sample size of 456, if the null hypothesis
is true:
