What are the 5 hypothesis steps?
2. 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 mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of 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?
And the Hypothesis setup:1.
Here are the 5 steps:
1. State hypothesis and alternate. 2. Level of significance. 3. Identify test statistic. 4. Formulate decision rule. 5. Make the decision to accept or reject null hypothesis.
1. State hypothesis and alternative hypothesis
Null Hypothesis: It takes 42.3 minutes to assemble a ...
