A cola-dispensing machine is set to dispense 11 ounces of cola per cup, with a standard deviation of 1.0 ounce. The manufacturer of the machine would like to set the control limit in such a way that, for samples of 35, 5% of the sample means will be greater than the upper control limit, and 5% of the sample means will be less than the lower control limit. At what value should the control limit be set? (Round z values to two decimal places. Round your answers to 2 decimal places.)

  1. At what value should the control limit be set? (Round z values to two decimal places. Round your answers to 2 decimal places.)
  1. If the population mean shifts to 10.7, what is the probability that the change will not be detected? (Round your intermediate calculations to 2 decimal places and final answer to 4 decimal places.)
  1. If the population mean shifts to 11.7, what is the probability that the change will not be detected? (Round your intermediate calculations to 2 decimal places and final answer to 4 decimal places.)

A coffee machine is supposed to dispense 12 ounces of coffee in each cup. A business using one of these machines is concerned that it is dispensing less than 12 ounces. An inspector takes a sample of 16 cups of coffee, and finds a mean of ¯x=11.7x¯=11.7 ounces with a standard deviation of s=0.8s=0.8 ounces. (Assume coffee serving volumes are normally distributed.) 1. What are the null and alternate hypotheses for this study? H0: μ (< > ≤ ≥ =...

Exercise 6-73 Algo It is well documented that a typical washing machine can last anywhere between 5 to 20 years. Let the life of a washing machine be represented by a lognormal variable, Y = eX where X is normally distributed. In addition, let the mean and standard deviation of the life of a washing machine be 8 and half years and 6 years, respectively. [You may find it useful to reference the z table.] a. Compute the mean and...
