Provide an appropriate response.A study was conducted 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. Construct a 95% confidence interval for μ1 – μ2.

Provide an appropriate response.Test the hypothesis that μ1 = μ2. Two samples are randomly selected from normal populations. The sample statistics are given below. n1 = 25 n2 = 30 1 = 23 2 = 21 s1 = 1.5 s2 = 1.9

Provide an appropriate response.Test the hypothesis that μ1 = μ2. Two samples are randomly selected from normal populations. The sample statistics are given below. n1 = 25 n2 = 30 1 = 31 2 = 29 s1 = 1.5 s2 = 1.9

Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.A researcher randomly selected 100 adults aged 18-25 and 100 adults aged 50-60. Within each age group, she recorded the number of smokers.
