We wish to estimate what percent of adult residents in a certain county are parents. Out of 100adult residents sampled, 67 had kids. Based on this, construct a 90% confidence interval for theproportion, p, of adult residents who are parents in this county.Give your answers as decimals, to three places.

Given : n = 100 x = 67 Confidence level = 90% p = x/n = 67/100 = 0.67 Z value at 90% confidence = 1.645 90% Confidence interval = p ± Z * p(1-p)n = 0.67 ± 1.645 * 0.67*0.33100 = 0.67 ± 0.0470 = (0.623, 0.717) 0.623 < p <0.717

When you are done, click here to see a summary of your score Question with last attempt is displayed for your review only In a certain school district, it was observed that 29% of the students in the element schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 130 out of 373 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? P=0.34 (Report answer as a decimal accurate to 2 decimal places.
