Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “During the average workday, how many hours do you spend conducting online research?” For the subsample of legal professionals (n = 250), the mean response was M = 2.7 hours, with a sample standard deviation of s = 4.5 hours.

- Do you ever get the feeling that you’re being watched? It has been suggested that the feeling of being watched often compels people to bring their behavior “into conformity with normative expectations they associate with their social environment.” A researcher wanted to find out if creating the feeling of being watched would affect her coworkers to be more charitable. She places a collection jar in the breakroom at the office to raise funds for a colleague with high medical expenses. Every other day, she tacks a poster of a pair of eyes to the breakroom bulletin board, to give those passing by the feeling of being watched. Total donations made on days with and without the poster on the bulletin board over a 20-day period are measured. Does the feeling of being watched make people more inclined toward charitable giving? What test should you use and why?What do you think are the respective research advantages and disadvantages of asking open questions and closed questions? Note: Please type the answer I need to copy paste it. Thank youDairy cattle are cattle that are bred for their ability to produce large quantities of milk. Lameness is a condition that can be detrimental to cattle since it can be painful and result in deleterious effects on the animal’s welfare. It is a condition in which cows have difficulty moving and especially walking. Investigators are interested in whether milk production in dairy cows is associated with whether or not the cow becomes lame. They think that the age of the cow (young or old) may confound and/or modify the relationship between milk production and lameness and so they collect information on the age of the cows as well. The data that cross classifies lame status and milk production status is stratified by age and provided in the tables below. Use SAS to complete each part. (a) Ignoring age, report the estimate for the OR and its corresponding 95% confidence interval. Interpret both. (b) Ignoring age, is milk production associated with lameness?
