However, in the special program for talented and gifted children, 100 out of 349 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 a = 0.05 level of significance. What is the hypothesized population proportion for this test? р — (Report answer as a decimal accurate to 2 decimal places.
