Answer:
The answer is below
Step-by-step explanation:
The procedure of selecting a sample is thus called, fulfilling two fundamental properties:
-All individuals in the population have the same probability of being elected.
-All samples of the same size are equally likely.
From a mathematical point of view, simple random sampling is performed assuming that the population has infinite elements. In practice, it is often the case that the populations to be considered have a very large number of elements, which can be compared to a situation with infinite elements.
Yes, it is possible to sample data instances using a distribution different from the uniform distribution.
In excel, do the following to obtain a sample dataset.
E.g. to create a 5 element sample from the standard normal distribution, place the formula = NORM.S.INV (RAND ()) in cell A1, highlight the range A1: A15 and press Ctrl-D.
Answer:
The t value for 99% CI for 21 df is 2.831.
The critical value that should be used in constructing the confidence interval is (64.593, 86.407).
Step-by-step explanation:
Now the sample size is less than 30 and also population standard deviation is not known.
Then we will use t distribution to find CI
t value for 99% CI for 21 df is TINV(0.01,21)=2.831
The margin of error is 
Hence CI is
Answer:
11.36
Step-by-step explanation:
Answer: 5p - 4
5 times ‘p’ = 5p
4 less than ‘p’ = p - 4
Therefore,
=> 5p - 4
