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 unknown. Compute test statistic for sample data that you would use to test whether sample mean varies from population mean of 10 pounds at a 5 percent level of significance in two-tailed test.
