Question 1

xt Course 2023SP Stataties MAX 00 Lei Edinity Write your answer in the box below. edfinity.com/assessments/630485452e5109007662408 04 (a) I am estimating the ability to throw a crumpled piece of paper into a wastebasket. I am using this class as a sample. Attempt to toss the paper into the basket ten times. How many times did the crumpled paper fall into the basket? • Place a wastebasket in a room away from any wall or piece of furniture, Stand approximately 8 to 10 feet from the basket. . From that position, throw a piece of crumpled paper into the basket. • Repeat the throw ten times. Record how many times the paper ends up in the basket. DOLL I will place your result into a table with the other student results. b) I want to choose a target population whose throwing ability can be described well with the paper-throwing statistics (average, median, standard deviation range...) that I received from the students in this class. Here are some candidate populations:

MAT 181 students that commute to class by car.
Students in my classes for this year and the last ten years.
Online Boston area students during the Pandemic.
Online Community College students that have live Webex or Zoom classes with required attendance.

Question 3

Sample annual salaries (in thousands of dollars) for employees at a company are listed.

Find the sample mean and sample standard deviation.
Each employee in the sample is given a $5%$ raise. Find the sample mean and sample standard deviation for the revised data set.
To calculate the monthly salary, divide each original salary by 12 . Find the sample mean and sample standard deviation for the revised data set.
What can you conclude from the results of (a), (b), and (c)?
The sample mean is $\overset{x}{ˉ} = 48.5$ thousand dollars.

Question 4

A researcher found a study relating the value of a car,

y

, to the age of the car,

x

. When researchers looked at the association of

x

and

y

, they found that the coefficient of determination was

r^{2} = 0.158

Select a conclusion that the researcher can make from this data.

The correlation coefficient, $r$ , is $0.842$ .
About $16%$ of the variation in value of the car is explained by a linear relationship with the age of the car.
About $40%$ of the variation in the age of the car is explained by a linear relationship with the value of the car.
The correlation coefficient, $r$ , is $0.025$ .
