The manager of a warehouse monitors the volume of shipments made by the delivery team. The automated tracking system tracks every package as it moves through the facility. A sample of 25 packages is selected and weighed every day. On the basis of contracts with customers, the mean weight should be μ = 22 pounds with o = 5 pounds. Mark the statement below as True or False. If you believe that the statement is false, briefly say why you think it is false. To have a small chance of for a Type II error, the manager of the warehouse should locate the control limits in the X-bar chart at 22 +3 pounds. Choose the correct answer below. A. True O B. False, this would focus attention on a Type I error and ignore the risk for a Type II error. O C. O D. False, this would ignore the risk for both a Type I and a Type II error. False, the control limits do not affect the chance of a Type Il error occurring.

Mark the statement below as True or False. If you believe that the statement
is false, briefly say why you think it is false.
To have a small chance of for a Type II error, the manager of the warehouse
should locate the control limits in the X-bar chart at 22 ± 3 pounds.
Choose the correct answer below.
A. True
False, this would focus attention on a Type I error and ignore the risk for
a Type II error.
O B.
O C.
O D.
False, this would ignore the risk for both a Type I and a Type Il error.
False, the control limits do not affect the chance of a Type II error
occurring.
Transcribed Image Text:Which is more likely to contain µ, the z-interval X± 1.960/√n or the t-interval
X±to.025, n-1S/√√n? Assume that the population variable x is normally
distributed.
Choose the correct answer below.
A. Both intervals are equally likely to contain μ with probability≈ 0.95.
B. The interval X ±to.025, n - 1S/√n has a higher probability of containing µ.
OC. The interval X± 1.960/√n has a higher probability of containing μ.
