Serhud [2]

Answer:

<h3>In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> t test</u></h3>

Step-by-step explanation:

In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> </u><u>t test</u>

<h3>For :</h3>
  • A t-test is one of the methods of a statistic and is used to determine if there is a significant difference between the two groups of their means based on a sample in data.  
  • The statistical significance is determined by the difference between the averages of group size , the sample size, and standard deviations of the groups.
<h3>Therefore option c) t test is correct</h3>

A rectangular garden is fenced on all sides with 256 feet of fencing. The garden is 8feet longer than it is wide. Find the lengt
Marina86 [1]
Perimeter = 2L + 2W = 256

"8 feet longer than it is wide"
translates to
L = 8 + W

we plug that into the first equation and get
2(8 + W) + 2W = 256
now we solve for W

distribute the 2
16 + 2W + 2W = 256

add like terms
16 + 4W = 256

subtract 16 from both sides
4W = 240

divide both sides by 4
W = 60

plug that into
L = 8 + W
and solve for L now

L = 8 + 60
so
L = 68

therefore your
length = 68
and
width = 60
