Question: The management of white Industries is considering a new method of assembling its three-wheel golf cart. The present method requires 42.3 minutes on the average to assemble a cart. The new method was introduced, and a time and motion study was conducted on a random sample of 24 carts. The mean assembly time was computed to be 40.6 minutes. The standard deviation of the sample was 2.7 minutes. Using the .10 level of significance, can it be said that the assemble time under the new method is significantly less than before?

  1. State the Null and Alternate Hypothesis:
  2. Which test statistic will you be using? State the critical value and the decision rule (when you would reject the null hypothesis). This is the same as stating the rejection area.
  3. Calculate the test statistic.
    d. Do you reject or fail to reject the Null Hypothesis? What do you conclude from the analysis?
