The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart. The meanassembly time for a random sampleof 24 carts, using the new method, was 40.6 minutes, and the standard deviationof the sample was 2.7 minutes. Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?
Students t test for the assembly time of golf cart. The students t test compare two methods. The solution gives students t test, decision rule, confidence level and test statistic with interpretation of results.
