Unit 6 Lab Stat Project

 

LAB Unit 6:Stat Project [(Required/Graded) 25 points) CSLO A.4,CSLO F.1,CSLO F.2, CSLO F.3,

 

CSLO F.4, CSLO G]

 

The goal of this lab is to standardize data, to compute probabilities using the standard normal

 

distribution, and to find values given probabilities. 1. Use Microsoft Excel to compute the mean and standard deviation of your RAW V3 data (as

 

listed in Lab

 

Mean:__________________________________

 

Standard deviation:___________________________

 

2. What are the mean and standard deviation you computed in Lab 3, Part 2?

 

Mean:__________________________________

 

Standard deviation: ___________________________

 

Are these values close to those in question 1? Explain clearly why they could be different. *** For the remainder of the labs, use the mean and standard deviation from question 1****

 

3.Sort the list of 40 data values from smallest to largest, using the Microsoft Excel . Write down

 

the raw scores

 

on lines #1, #20, and #40. Compute the corresponding z-scores by using the formula. Round to

 

two decimal

 

places.

 

Line #

 

x value

 

z - score

 

Value in table 4

 

1

 

Low value (L) = 20 Middle Value (M) = 40 High Value (H) = 4.Using the mean and standard deviation from #1 above, and using the formula x z , find

 

the data value x that goes with the following z-scores.

 

z ? score

 

z 2.50

 

z 3.20

 

z0

 

z 0.5 Use x and s . x value For the rest of the lab, you will make the assumption that your data is approximately nor

 

mally distributed. For some students this is a reasonable assumption; for others, it is not. If

 

you have any questions about this, please contact your instructor.

Find P( x> H). _______________________________________ 9

 

a)

 

b)

 

c)

 

d)

 

e) Sketch a normal curve using your value for .

 

Shade the area where the lowest 10% of your values would be.

 

What is the z ? score for this area. ___________________

 

Using the method from #4 above, find the x. value

 

Use this information to fill in the blanks. The first blank should be your name for x.

 

"10% of all _________________________ in my population are below ____________." 10

 

a) Sketch a normal curve using your value for .

 

b) Shade the area where the top 5% of your values would be.

 

c) What is the z ? score for this area. ___________________

 

d) Using the method from #4 above, find the x. value

 

e) Use this information to fill in the blanks. The first blank should be your name for x.

 

"5% of all _________________________ in my population are above ____________." Stat Project Points: 25 Points
