A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. The data shown below represent the amount of force required to break a sample of 30 insulators.

5. A manufacturing company produces electric insulators. To test the strength of the insulators, you apply a force to an insulator until it breaks. You measure the force by observing how many pounds are required to break the insulator. You collect the force data for a random sample of 30 insulators selected for this experiment. The data is in the Excel file for this assignment in the tab Force. a. Construct a 95% confidence interval estimate for the population mean...

You are curious about whether you can enhance the ability to hear differences between nonnative speech sounds when people learn a new language. You test your novel language training procedure on a group of 32 pariticipants using a pretest/posttest design. The pretest and the posttest measure performance as the number of correct trials out of 100. The data are shown on the right. Does the new language training procedure improve the perception of nonnative speech sounds? Number of correct items...

For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...
