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.

A meteorologist records the temperature (in degrees Fahrenheit) and the amount of rain (in centimeters) during a series of rain storms. Her data is below: Temperature 62 38 29 55 61 70 47 Rain amount 1.2 6.3 5.1 2.2 0.8 1.4 3.3 Based on this, she wants to determine whether the temperature influences how much rain will fall Answer each question below, romling all values to at least 2 decimal places. (a) Find an equation of the least-squares regression line based on this sample. (b) Use your answer from part. (a) to predict the amount of rain in a storm that takes place when the temperature is 58 degrees Fahrenheit. (If for any reason you could not complete part (a), use --2.5+ 0.15.x instead.) (c) Find the residual for a storm in 40-degree weather that creates 4.2 centimeters of rain.

Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise).

Sarah was calculating the speeds (mph) of vehicles travelling down Maple Street on two separate days at 9 am for an hour. Below is the data she collected. Wednesday's Speeds: Sunday's Speeds: 34,28,24,17,39,44,64,33,27,21,38,40,60,30,25,37,30,25,35,30 18,27,34,37,49.55,63,61,48,30,27,17,17,15,26,46,25 4) Find the Standard Deviation of each day.

You have the following data: Student A took 2 courses in the Fall semester. His previous CGPA was 3.2. He received GPA 3.5 in the Fall semester. Student B took 5 courses in the Fall semester. Her previous CGPA was 3.9. She received GPA 3.6 in the Fall semester. Student C took 4 courses in the Fall semester. His previous CGPA was 3.6. He received GPA 3.4 in the Fall semester. Using this data, we'll try to build a model using Least Square approximation, that can predict the CGPA of a student in the Fall semester given the number of courses s/he took in Fall, and his/her previous CGPA. (In real life, we'd use many more parameters, but for the sake of the quiz, we are keeping things simple.) The model is as follows - wi x (number of courses) + wz x (previouos CGPA) = GPA in Fall Find the values of wi, and wz using Least Square approximation. (Round off up to 3 decimal points) w, is equal to - wz is equal to - If a student took 4 courses in Fall, and his previous CGPA was 3.7, what would be…
