Answer:
Step-by-step explanation:
Given
Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;
n, in both datasets in 6
For A
For B
Next, calculate the sample standard deviation
This is calculated using:
For A
For B
Calculate the pooled variance
Lastly, calculate the test statistic using:
We set
So, we have:
The equation becomes
<em>The test statistic is 31.29</em>
89/100 as a precent is is 89% because if you change 89/100 to a decimal you get .89 and then you multiply that by 100 (or just move the decimal over 2 places to the right) and you will get 89% make since? and its the same way if your going from % to decimal except you divide by 100( or move the decimal over 2 places to the left) so to a percent is right and to a decimal is left. easy right?
Answer:
The correct answer is C. 224
Step-by-step explanation:
Sn = n/2 (2*A1 +d(x-1))
S7=7/2(2*17+5(7-1))
S7=7/2(34+30)
S7=7/2(64)
S7=7*64/2
S7=7*32/1
S7=224

Answer:
3 Miles
Step-by-step explanation:
The Median is the middle value of whatever data set, which means the median is 3 since its the middle value
