Question
In a certain school district, it was observed that 32% of the students in the element schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 84 out of 218 students are only children. The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district. Test at the α=0.05α=0.05 level of significance.
What is the hypothesized population proportion for this test?
p=p=
Choose the correct pair of hypotheses for this situation:
