The production line at the Heinz ketchup factory is calibrated to fill bottles of ketchup with no more than 24 ounces of ketchup in each bottle. We certainly do not want ketchup to spill onto the assembly line equipment; that would create a mess.

In order to test how well our machinery is working, a sample of 70 bottles are randomly selected from a days production of filled ketchup bottles and the contents of each bottle are measured. The sample reveled a mean of 24.1 ounces per bottle, with a sample standard deviation of 0.3 ounces.

Use an α = .05.

A. Provide the appropriate hypothesis test criteria:

HO: μ

  • =

HA: μ

  • <

  • >

B. Using the data from the sample, answer the five fill-in-the-blank questions, and make the correct hypothesis test conclusion.

Reject Ho if the test statistic of    is
  • >

  • <

the critical value of   
Reject Ho if the p-value of    is < the value of α of   

Based on these results, we should:

  • Reject Ho

  • Accept Ho

C. Should Heinz shut down the production line?

This question will be sent to your instructor for grading.

Expert Solution

We want to test that the production line at the Heinz ketchup factory is calibrated to fill bottles of ketchup with no more than 24 ounces of ketchup in each bottle.

u :- Population mean amount of ketchup in each bottle.

x:-  ketchup amount in each bottle

We have to test

Ho:- Population mean amount of ketchup in each bottle is less than or equal to 24 ounces

vs

H1:- Population mean amount of ketchup in each bottle is greater than 24 ounces.

C)

Yes

As we have concluded that the mean is more than 24. Heinz has to shut down production.

French’s going up against the ketchup giant, Heinz, and another well entrenched brand in the President’s Choice ketchup. As such, French’s is facing some significant challenges as it expands into and attempts to gain significant share of the Canadian market. Suggest a revised pricing and communications strategy that will help them to succeed in this expansion. Consider how French’s can move forward to present its ketchup, which may stimulate greater demand pull from the Canadian population.

A requirement to sense glass bottles leaving an automatic washer on a production line conveyor belt has been notified to you. The output from the sensor is to be of binary form, i.e. logical 1 when the part is present and logical 0 when no part is present. It is also necessary to ensure that a change of sensor state occurs closer to the sensor when a bottle approaches than when it moves away. The switching distance will lie between...

A paint manufacturer fills cans of paint using a machine that has been calibrated to fill the cans to contain an average of 1 gallon (128 ounces) each. To test whether their machine has come out of calibration, the manufacturer takes a random sample of 100 cans and finds that they average 128.2 ounces with a sample standard deviation of 4 ounces, and the volume of paint in the cans is normally distributed. Is this strong evidence that the can-...

A production line operation is designed to fill cartons with laundry detergent to a mean weight of 64 ounces. A sample of cartons is periodically selected and weighed to determine whether underfilling or overfilling is occurring. If the sample data lead to a conclusion of underfilling or overfilling, the production line will be shut down and adjusted to obtain proper filling. (a) Formulate the null and alternative hypotheses that will help in deciding whether to shut down and adjust the...
