In a test of hypothesis, the null hypothesis is that the population mean is equal to 60 and the alternative hypothesis is that the population mean is not equal to 60. A sample of 36 elements selected from this population produced a mean of 63 and a standard deviation of 6.3. What is the approximate p-value for this test?© BrainMass Inc. brainmass.com June 3, 2020, 10:09 pm ad1c9bdddf
Given xbar=63, s=6.3 and n=36. We can calculate the test z-statistic
The solution examines p-values and the null hypothesis.
