Transcribed Image Text:In a certain school district, it was observed that 28% of the students in the element schools were
classified as only children (no siblings). However, in the special program for talented and gifted children,
117 out of 369 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 = 0.02 level of significance.
What is the hypothesized population proportion for this test?
p=
(Report answer as a decimal accurate to 2 decimal places. Do not report using the percent symbol.)
Based on the statement of this problem, how many tails would this hypothesis test have?
O one-tailed test
O two-tailed test
Choose the correct pair of hypotheses for this situation:
0.317 Ho:p
0.28 Ho:p = 0.28 Ho:p = 0.28
(A) (B)(C) H:p < 0.28 Ha:p+ 0.28 Ha:p > 0.28
0.317 Ho:p = 0.317
Ha:p < 0.317 Ha:p + 0.317 Ha:p > 0.317
Ho:p
Ho:p
(D) (E) (F)
(A) (B)
(D) (E)
Using the normal approximation for the binomial distribution (without the continuity correction), was is
the test statistic for this sample based on the sample proportion?
= z
(Report answer as a decimal accurate to 3 decimal places.)
You are now ready to calculate the P-value for this sample.
P-value =
(Report answer as a decimal accurate to 4 decimal places.)
