In a systematic random sample of size n
drawn from a population of size N, how many random numbers
need to be generated to identify those subjects who are included in
the sample?
n
N/n
N-n
1
n-1
while selecting a systematic sample of size "n" from a population of size we select only first object radnomly while other objects we will select in a specefic pattern
so first we calculate then we select first number "i" randomly with i<k and then we select every kth number from that so we need to select only first number randomly hence correct option is

A random sample of size n is to be drawn from a population with a mean =900 and standard deviation =200 .What size sample would be necessary in order to ensure a standard error of 25 ?
A random sample of size n is to be drawn from a population with the mean being 800 and the standard deviation being 300. What size sample would be necessary in order to reduce the standard error to 10?
A simple random sample of size n = 20 is drawn from a population that is normally distributed. The sample mean is found to be x = 66 and the sample standard deviation is found to be s = 10. Construct a 90% confidence interval about the population mean.

A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, is found to be 110, and the sample standard deviation S is found to be 25. Construct a 99% confidence interval for if the sample size n = 21
1o) A simple random sample of size n is drawn! from a population that is normally distributed The sample mean x is found to be 108, and the sample Standard deviation, s, is found to be lo. Construct a go.i. confidence interval for N, if the sample size, n, is 25.
A simple random sample of size n is drawn from a population that is known to be normally distributed. The sample variance, s?, is determined to be 13.2. Complete parts (a) through (c). (a) Construct a 90% confidence interval for o2 if the sample size, n, is 20. The lower bound is (Round to two decimal places as needed.)
