Answer #1

1)Ho: BMI of native born and foreign born New york city residents is equal
or
Ho: BMI(native)=BMI(foreign)
vs
H1:BMI of native born and foreign born New york city residents is not equal.

2)When variances are assumed to be equal
t-value=5.78
When variances are assumed to be unequal
t-value=5.80

3)p-value as shown in the output is 0.000

4)Since p-value is <0.05 we reject our null hypothesis.

5)The conclusion that follows from rejection of null hypothesis is:
BMI of native born and foreign born New york city residents is not equal
