quest hat hypothesis testing procedure should you use to answer ssume all samples are simple random samples, and assume x = 0.05 if it isn't ecified. random sample of size 21 was taken from a normal population. The sample = 0.05, erage was 9.87 and the population SD is known to be 1.17. Assuming α = What test should you use for testing whether the population mean equals 9.7? One sample z-test for the population mean. Two sample z-test for the population means. One sample z-test for proportions. Two sample z-test for proportions. One sample t-test for the population mean. None of our hypothesis tests fit. 23
