Answer:
1. area of new pen = 11

2. i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
Step-by-step explanation:
The size of the pen as planned = 5 ft long by 4 ½ ft wide
Area of the pen = length x width
= 5 x 4 ½
= 5 x 
Area of the pen = 
= 22 ½ 
But, Krista has to make the pen ½ the size of planned. So that;
area of new pen = ½ x 22 ½
= ½ x 
= 
= 11 
area of new pen = 11

The area of the new pen would be 11
.
The possible values she could use are:
i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
Answer:
Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
Is there any more details, I could give a better answer.
the answer is 10x
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
x
=
10
Answer:
Option b.
Step-by-step explanation:
Given that a repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10
A matched pair hypothesis test is conducted for the difference in the means for the pairs.
If 11 pairs i.e. 22 entries are compared thenwe have degrees of freedom = 11-1 =10
b. 11 for repeated and 22 for matched
is right answer.
Note: The degrees of freedom (DF) is:
DF = n - 1
where n is the number of paired observations.
