The Cоunty Cоmmissiоner is аlso interested in recent town-level developments in locаl policymаking. Specifically, three years ago, several of the towns in Cloudy County decided to provide local funding for universal daycare. The County Commissioner wonders whether average weekly wages are different between towns that do and do not provide universal daycare and asks you to investigate. Luckily, when you collected that sample of 400 adults, you also asked them whether they have access to universal daycare and what they typically earn in one week. You calculated the following information:   Among adults with access to universal daycare: Mean weekly wage: $808 Standard deviation: $27 Sample size: 150   Amount adults without access to universal daycare: Mean weekly wage: $800 Standard deviation: $32 Sample size: 250   Fulfill the County Commissioner’s request by completing parts a through g below. a.
