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. Do not report using the percent symbol.)

Please do not give solution in image format thanku Newborn babies are more likely to be boys than girls. A random sample found 13,173 boys were born among 25,468 newborn children. The sample proportion of boys was 0.5172. Is this sample evidence that the birth of boys is more common than the birth of girls in the entire population?
Please do not give solution in image format thanku Do our children spend enough time enjoying the outdoors and playing with friends, or are they spending more time glued to the television, computer, and their cell phones? A random sample of 250 youth between the ages of 8 and 18 showed that 160 of them had a TV in their bedroom and that 90 had a video game console in their bedroom. Estimate the proportion of all 8- to 18-year-olds who have a TV in their bedroom and calculate the 95% margin of error for your estimate. (Round your margin of error to three decimal places.)
please show all steps and please write out complete SENTENCES as to how you did each step. And explaining what you did to get the answer!!! Thanks
Use the 7 step test. (or 5 Step) The Donaldson Corporation wants to hire a temporary secretary. There are two employment agencies in town, and it is believed that the average hourly wage charged by both agencies is the same. A Donaldson manager surveyed other employers in town to find what they paid the agencies for temporary secretaries. The results are summarized below. At, test the claim that each agency charges the same hourly wage. Imported wine: X-bar_1 =$9.55/hour ; s_1 =$1.45/hour ; n_1=20 Domestic wine: X-bar_2 =$9.25 ; s_2 =$1.25 ; n_2 =18
