Q1) Assume average puppy weighs 10 pounds. Sample of 10 puppies yields sample mean of 13.2 pounds and sample standard deviation of 2.78 pounds. Suppose population standard deviation is known to be 5.25. You wish to test whether sample mean varies from population mean of 10 pounds at 5 percent level of significance using two-tailed test. Compute test statistic for the sample data.

Q2) Woody is interested in determining if workers are more concerned with job security or pay. He gains cooperation of 30 individuals who work in different settings and ask each employee to rate his or her concern about salary levels and job security on scale from 1-10.
