Hello, I need help with answering the fowling problems. Thanks.

For the following dataset

4,5,9,6,8,10,3, 7,18,13,20, 16,14, 11, 15

Calculate a 20% trimmed mean.

STEP 1:Arrange the data set in order.Enter the numbers in ASCENDING order from left to right.

STEP 2:Identifyhow many observations,n,are there in the dataset.

n= []

STEP 3:Find 20of the number of observations.That is,find20% of the value for n you have found in the previous question.

20% ofn

20% of 15 = []

Enter a number.

STEP 4:Remove theappropriate number of pieces of observations from the data set.

The three lowest

The three highest

The threelowest ONLY

The three highest ONLY

STEP 5:Remove the appropriate SIX observations.

Enter the observations (smallest to largest)that should be removed from the data setin order to calculate the 20% trimmed mean.

STEP 6:Calculate the 20%trimmed mean.

After the 6 observations (3 smallest and 3 largest) have been removed, the following data remains

Find the mean of the above set of numbers. This is the 20% trimmed mean.

Sumof the Observations =

Number of Observations =

20%Trimmed Mean =

(ROUND TRIMMED MEAN TO ONE DECIMAL PLACE->XX.X)
