Water is pumped into the container from the top at a constant rate of per hour. Each member of the population has an equal and known chance of being selected. This discussion closely relates to:. Under these conditions, stratification generally produces more precise estimates of the population percents than estimates that would be found from a simple random sample. Try to explain history of Tupperware water container.

Since the rate is not constant. If the population is very skewed, you will need a pretty large sample size to use the CLT, however if the population is unimodal and symmetric, even small samples are ok. Visitors to this page also searched for:. Cluster Sampling is very different from Stratified Sampling. With cluster sampling one should divide the population into groups clusters. Please use the answer wisely.

Sample does not have known probability of being selected as in convenience or voluntary response surveys Probability Sampling In probability sampling it is possible to both determine which sampling units belong to which sample and the probability that each sample will be selected.

Although the Central Limit Theorem tells us that we can use a Normal model to think about the behavior of sample means when the sample size is large enough, it does not tell us how large that should be. Part c Determine the rate of increase of the height of water level in the container when the height is 9 m. Best maths T teacher ever! Was this answer helpful? Under these conditions, stratification generally produces more precise estimates of the population percents than estimates that would be found from a simple random sample.
