• Testing a Null Hypothesis on a Random Sample of 100

  Since the decision rule is "reject the null hypothesis when Z-test statistics value is greater than Z-table value", we reject the null hypothesis. 8.20 Use a rejection point to test null hypothesis versus alternate hypothesis by setting probability

• Statistics and Hypothesis Testing Problems

  Test the claim about the population mean at the given level of significance using the given sample statistics. Claim: < 1000; = 0:05; Sample statistics: x = 988, s = 29, n = 50. The null hypothesis: µ>=1000.

• Hypothesis testing: Hypothesis by Professor Brainstorm

  Subsequently researchers collect data and calculate the statistics of interest. If the observed statistics fall in the rejection region, the null hypothesis is rejected. If not, the null hypothesis is failed to be rejected.

• Two sample test of hypothesis of a population

  Test Statistics: The test statistics of the difference between the two populations mean is given by, Z = Z = = 1.2556 Decision Rule: If the test statistics value is less than the critical value then we have to accept the null hypothesis

  Using the smaller standard deviation, the test statistics value is increased and we will be able to reject the null hypothesis with smaller standard deviation. Please see the Excel document for the data.
