The County Commissioner is also interested in recent town-level developments in local policymaking. 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. Write the null and alternative hypotheses.   

Neighboring Sunny County heard about your excellent work for Cloudy County and hires you to help finish a project that was half completed by the previous analyst, who abruptly quit. This involves interpreting code and output from Stata that the previous analyst left in a file. The data you are working with is from a survey of a simple random sample of residents of Sunny County. The variable support is a dummy variable that is equal to 1 if the respondent supports a new levy to pay for schools and equals 0 if the respondent does not support the levy. You find the following code and output: a. What is the sample size of this dataset? [2 pts]  

Submit your work from the previous question (ie hand calculation of the test statistic) as one file (either a picture of your written work or an upload of a word document showing your work). Note: this question is not marked as any points, but affects the grade from the previous question (allows me to confirm you did the work; allows me to award partial credit in the case of a small mistake).

d. Using alpha=.05, should you reject or fail to reject the null hypothesis? Why?
