John was calculating the peeds (mph) of vehicles traveling down Maple Street on two separate days at 9am for an hour. Below is the data she collected.Wednesday's speeds: 32,28,24,17,39,44,64,33,27,21,38,40,60,30,25,37,30,25,35,30Sunday's speeds: 18,27,34,37,49,55,63,61,48,30,27,17,17,15,26,46,251. Calculate the mean and median of each day.2. Calculate the five-number summary of each day.a. Wednesday's Five-Number Summary.b. Sunday's Five-Number Summary.3. Test each day for outliers. If they have outliers, identify them and adjust the five-numbersummary to reflect the outlier. (Remember to find IQR and then Upper and Lower Limits)a. Wednesday's Outlier Testb. Sunday's Outlier Test4. Create a stacked box-and-whisker plot using the five-number summaries from Wednesday andSunday.5. What do you notice about the box-and-whisker plots? Describe the spread in each specifically.

There is a lot of data that we could collect about individuals on a treadmill, like data on the type of exercise(walking, jogging, running), or data on how they exercise/20mi mins, 30 mins, hour). List three more examples of each type of data, and how the data would be measured.
Meghan is a psychology major who is testing a maze for a group of mice to navigate. In order for it to be productive for a class project, she would like the average time for a mouse to complete the maze to be 90 seconds. She randomly selects 28 mice and has each mouse complete the maze. Meghan records the time, in seconds, that each mouse needed to complete the maze. The results are provided in the accompanying data table. Based on research and previous results, Meghan assumes that the population is normally distributed and the population standard deviation is 5.80 seconds. Use Excel to test whether the mean amount of time a mouse completes the maze is 90 seconds, and then draw a conclusion in the context of the problem, where α=0.10.

Suppose classmates who graduated in 2004 compared their median incomes ten years later. The bar graph displays the median income, in thousands of dollars, for each classmate during the time intervals from 2005‑2009 and 2010‑2014. For the individual with the largest dollar value increase in median income over the two time intervals, determine the amount of increase.
(For Questions 17-19 and 20-24). The following data was collected from a clinical trial testing a new drug aimed to lower blood pressure for individuals older than age 45. Half of the 20 participants received the new drug (Treatment = Yes) and the other half of the participants received a placebo pill (Treatment = No). Their age and gender was also recorded. Please use this data for Questions 17-19 and 20-24 and note, not all the information in the table will be used for either problem, you must decide what is relevant based on what the problem is asking.

An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and number of days until deaths began in each later group: Distance xx 2 5 4 4 4 6 Days yy 4 21 29 40 47 49 Use a calculator or software to find the following values. (a) Find the mean and standard deviation of xx. MEAN: STANDARD DEVIATION: (b) Find the mean and standard deviation of yy. MEAN: STANDARD DEVIATION: (c) Find the correlation rr between xx and yy. r:
