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>
200+400=600 u just add 2 and 6 togather and u get 6 and then annd the two zeros on too it
Answer:
n = - 3 and k = 100
Step-by-step explanation:
We are given that ......... (1) and we have to find k and n which are constants.
Now, from equation (1), we can write
⇒
Now, for z = 100, x =1 and for z = 25/2, x = 2
Hence,
⇒
⇒ n = - 3
Now, from equation (1) we get
⇒
⇒ k = 100 {Since, x = 1, when z = 100}
Therefore, n = - 3 and k = 100 (Answer)
The next number in the pattern would be 14.03.
To find this, note the differences found by subtracting each number from the number that comes after.
4.03 - 2.78 = 1.25
5.78 - 4.03 = 1.75
8.03 - 5.78 = 2.25
10.78 - 8.03 = 2.75
Since each difference goes up by .5 each time, we know we can add .5 to the last difference to find the newest one.
2.75 + .5 = 3.25
Now we have the difference, so we add that to the last number.
10.78 + 3.25 = 14.03
