Imagine that the average weight of a total of 500 girls in a high school is 35kg. Tom randomly sampled 10 girls and measured the
ir weight. And then he repeated this procedure for three times. The means and standard deviations are listed as following. Which sample estimate shows the least sample variability?
1 answer:
Answer:
The sample 2 has a lowest value of SE corresponding to the least sample variability.
Step-by-step explanation:
As the value of the sample means and standard deviations are not given, as similar question is found online from which the values of data is follows
The data is as attached with the solution. From this data
Sample 1 has a mean of 34 and a SE of 5
Sample 2 has a mean of 30 and a SE of 2
Sample 3 has a mean of 26 and a SE of 3
Sample 4 has a mean of 38 and a SE of 5
As per the measure of the sample variability is linked with the value of SE or standard error. Which is lowest in the case of sample 2 .
So the sample 2 has a lowest value of SE corresponding to the least sample variability.

Answer:
Step-by-step explanation:
Given the Geometric sequences:
1. ___, 24, ___, ___, 3/64
2. ___, 1/4, 1/2, ___
3. 81, ___, ___, ___, ___, 1/3
To find:
The values in the blanks of the given geometric sequences.
Solution:
First of all, let us learn about the term of a geometric sequence.
Where is the first term and
is the common ratio by which each term varies from the previous term.
Considering the first sequence, we are given the second and fifth terms of the sequences.
Applying the above formula:
Solving the above equation:
Therefore, the sequence is:
Considering the second given sequence:
Therefore, the sequence is:
Considering the third sequence:
Therefore, the sequence is:
