There are many products that on their label, establish a content of the packaging. Select a brand of cleaning detergent (for example ACE or Tide). In their label, they establish a weight of the amount of detergent in each box. Choose a sample of 8 boxes from the selected company and weight the 8 samples on a scale. Collect this information and build a hypothesis test, a confidence interval, a P – value and size of sample (n) by comparing the average weight of the samples with the one on the box label. It determines, through the hypothesis test, if there is any difference in the average weight of the sample boxes with the one that appears in the box. Use an alpha for this 0.01 test. What is your conclusion?

A researcher hypothesizes that different colors of cars result in different average speeds. To test this claim, she took a random sample of 20 people who own 4 different colors of colors of cars (n = 20, N = 80, G = 4), and she then tracks their average speed on the highway for a week of driving. The following ANOVA table has some of her results. Please help her answer her research questions by completing the following ANOVA table below and answering the follow-up questions.

Irondale County has two school districts, Anaconda and Copper Canyon. In the Anaconda School District, the average score of fifth graders on the Iowa Test of Basic Skills (ITBS) was 50. In the Copper Canyon School District, the average ITBS score for 5th graders was 72. Can we conclude that the average score for all fifth graders in Irondale County who took the test is 61, the mean of 50 and 72? If so, explain why. If not, tell what additional information would be needed in order calculate the mean ITBS score for all their fifth graders.
