A group of students got the following scores in a test:6,7,8,12,13and 15. Consider samples of size 3thag can be drawn from this population. List all the possible samples and the corresponding mean.
State whether the following statement are true or false and also give the reason in support your answer
In a big hall there are 50 rows and each row has 60 students. A research scholar selects 10 rows randomly and then randomly selects 15; students from each selected row. It is an example of cluster sampling procedure.
State whether the following statement are true or false and also give the reason in support your answer
(1)As we increase the sample size, representativeness of the population by the sample decrease
.
Neon gas is used in manufacturing to create signs. If you run an electric current through the gas,
it will glow in neon colors. Unfortunately, when you run electricity through the gas, its
temperature increases. If the temperature starts at 50⁰C, it will raise to about 150⁰C after the
sign is on for 4 hours. The gases original volume was 5 L. What is the volume of the gas after
the sign is on for 4 hours
A system has constant volume (ΔV=0) and the heat around the system increases by 50 J.

Problem: A researcher is conducting a study about the effectiveness of a new product to the households in a certain Barangay. His population consists of the numbers 8, 4, 2, 1, 13, and 10. Let us list all possible sample size of 4 from this researcher and compute the mean of each sample.
1. Determine the number of sets of all possible random samples using the combination formula.
2. List all the possible samples and compute the mean of each sample.
3. Construct the sampling distribution.
4. Construct the histogram.
what adaptation must be nedeed for radially and bilaterally symetrical invertebrate to survive in a given environment?
Consider a population consisting the scores of 6 students in a Statistic Test.
18, 22, 25, 28, 32, 36
Suppose samples of size 3 are drawn from this population, describe the sampling
distribution of the sample means following the steps below.
Step 4: List all possible
samples and their
corresponding means.
