- Over a long period of time, the production of 1000 high-quality hammers in a factory seems to have reached a weight with an average of 971? and standard deviation of 15.2 ?. Propose a model for the weight of the hammers including a probability distribution for the weight. What are the assumptions for this model to hold? What parameters does this model have?A new production system is configured, and one wants to evaluate if the new system makes more constant weights. For this a random sample of newly produced hammers is evaluated yielding the following weights: 987,966,955,977,981,967,975,980,953,972What hypothesis can you formulate and what test and decision rule can you make to estimate if the new system produces a more constant weight? Express these assertions as logical statements involving critical values. What error probabilities can you suggest and why? Calculate the ?-value. Perform the test and express conclusions.Over a long period of time, the production of 1000 high-quality hammers in a factory seems to have reached a weight with an average of 971? and standard deviation of 15.2 ?.
