A study was conducted by a local city council to determine if the salaries of librarians from two neighboring cities were equal. A sample of 15 librarians from each city was randomly selected. The mean from the first city was $28,900 with a standard deviation of $2300. The mean from the second city was $30,300 with a standard deviation of $2100. Analysis the data using a hypothesis test and advise the council of your findings. Use a=0.05 .

a) Hypothesis :

A study was conducted to determine if the salaries of elementary school teachers from two neighboring districts were equal. A sample of 15 teachers from each district was randomly selected. The mean from the first district was $28,900 with a standard deviation of $2300. The mean from the second district was $30,300 with a standard deviation of $2100. Assume the samples are random, independent, and come from populations that are normally distributed. Construct a 95% confidence interval for μ1 -...

A study is conducted to compare salaries of managers of a certain industry employed in two areas of the country, the eastern and northern regions. Independent ran dom samples of 300 plant managers are selected for each of the two regions. These managers were asked for their annual salaries. The results showed an average salary x1 = $102300 and standard deviation s1 = $5700 for the eastern region and an average salary x2 = $98500 and standard deviation s2 =...

A study was conducted to determine if there was a difference in the humor content in British and American trade magazine advertisements. In an independent random sample of 270 American trade magazine advertisements, 56 were humorous. An independent random sample of 203 British trade magazines contained 52 humorous ads. Do these data provide evidence at the 0.05 significance level that there is a difference in the proportion of humorous ads in British versus American trade magazines? State the null and...

A study was conducted to determine if there is a difference between the investing preferences of midlevel managers in the public and private sectors in New York City. A random sample of 320 public-sector employees and 380 private-sector employees was taken. The sampled participants were then asked about their retirement investment decisions and classified as being either “aggressive,” if they invested only in stocks or stock mutual funds, or “balanced” if they invested in some combination of stocks, bonds, cash,...
