Simplot.com. One of its major products is french fries that are sold primarily on the commercial market to customers such as McDonald's and Burger King. French fries have numerous quality attributes that are important to customers. One of these is called dark ends, which are the dark-colored ends that can occur when the fries are cooked. Suppose a major customer will accept no more than 0.06 of the fries having dark ends.Recently, the customer called the Simplot Company saying that a recent random sample of 300 fries was tested from a shipment and 27 fries had dark ends. Assuming that the population does meet the 0.06 standard, what is the probability of getting a sample of 300 with 27 or more dark ends?A) 0.0341
B) 0.0162
C) 0.0012
D) 0.0231
Q. 2The chance of making a Type II statistical error increases if the true population mean is closer to the hypothesized population mean, all other factors held constant.
Indicate whether the statement is true or false
Q. 3The Brockingham Carpet Company prides itself on high quality carpets. At the end of each day, the company quality managers select 3 square yards for inspection. The quality standard requires an average of no more than 2.3 defects per square yard.
The expected number of defects that the inspector will find during the inspection is 6.9. Indicate whether the statement is true or false
Q. 4Which of the following is an assumption for the one-way analysis of variance experimental design?
A) All populations are normally distributed.
B) The populations have equal variances.
C) The observations are independent.
D) All of the above
Q. 5United Manufacturing and Supply makes sprinkler valves for use in residential sprinkler systems. United supplies these valves to major companies such as Rain Bird and Nelson, who in turn sell sprinkler products to retailers.
United recently entered into a contract to supply 40,000 sprinkler valves. The contract called for at least 97 of the valves to be free of defects. Before shipping the valves, United managers tested 200 randomly selected valves and found 190 defect-free valves in the sample. The managers wish to know the probability of finding 190 or fewer defect-free valves if in fact the population of 40,000 valves is 97 defect-free. The probability is:A) 0.0111
B) 0.0612
C) 0.0475
D) 0.0212
