Tim and Nick are borthers. Tim is researching the relationship between the average word length in different books and the grade level associated with the books. Tim takes a representative sample of the word lengths in a book from his fifth-grade class. He then performs the same sampling process for one of Nick's school books. The sampling results are shown in these plots. Part A: Based on the data from the plots, estimate the median word length in each book. What does the median word length represent in your own words? Provide evidence to support your answer.

Part B: Based on the data from the plots, estimate the mean and the mode wor dlength in each book. Round to the nearest hundredth, and compare these to the medians you found in Part A. At which grade level do you think Nick's book is written? Explain your reasoning.

Part C: Tim conducted that his book has no words longer than 10 letters and Nick's book has no words longer than 7 letters. Is Tim Correct? Why or why not?

Part D: Based on the data in the plots, what might the mean, median, and mode lengths be for an eighth-grade book? Explain your reasoning.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
