Large counts condition
The conditions we need for inference on a mean are: Random: A random sample or randomized experiment should be used to obtain the data. Normal: The sampling distribution of x ¯. . (the sample mean) needs to be approximately normal. This is true if our parent population is normal or if our sample is reasonably large ( n ≥ 30) .To construct a confidence interval for p p p, check the following conditions: Random: The data come from a random sample from the population of interest. Large Counts: Both n p ^ n\hat{p} n p ^ and n (1 − p ^) n(1-\hat{p}) n (1 − p ^ ) are at least 10 10 10. Latoya interviews an SRS of the students living in the dormitory, so the condition ...

Comparing to Law of Large Numbers, because it require "less data", it has a relaxation in conclusion: not converge to a number, it converge to a normal distribution. Thanks for Yuri and Antoni's links, I think my question is different from the two questions linked. For question . Central limit theorem versus law of large numbersLarge Counts Condition: The large counts condition, also known as the "success-failure" condition, is used when applying certain statistical methods to categorical data. It states that for these methods to be valid, both the number of successes and failures must be at least 10.Large Counts Condition: For the large counts condition to be met we need np₁ > 5, nq₁ > 5, np₂ > 5, and nq₂ > 5, where n is the sample size, and p and q represent the success and failure probabilities, respectively. With n = 50 and the number of successes being either 13 or 16, it is clear that this condition is also met (as 13 and 16 ...

(c) Is the sampling distribution of approximately Normal? Check to see if the Large Counts condition is met. (d) Of the poll respondents, 44% said they did attend church last week. Find the probability of obtaining a sample of 1785 adults in which 44% or more say theyLarge Counts Condition: This means that we should expect at least 10 successes (tails) and 10 failures (heads). This is based on the np ≥ 10 and n(1-p) ≥ 10 rule, where 'n' is the number of trials and 'p' is the probability of success.Stuck on a STEM question?

O No. The 10% condition is not met. No. The Normal/Large Counts condition is not met because the sample size is too small and the shape of the distribution of differences is not known. O Yes. All conditions are met.…

The Large Counts Condition, part of the requirements for the Central Limit Theorem to apply, stipulates that we must expect at least 10 successes (excellent ratings) and 10 failures (not excellent ratings) in the sample. Since 20 out of 22 responses rated the food as excellent, this condition is not met, because there are only 2 failures. ...Large Counts Condition: The large counts condition, also known as the "success-failure" condition, is used when applying certain statistical methods to categorical data. It states that for these methods to be valid, both the number of successes and failures must be at least 10.
No, the Large Counts Condition is not met. A local school board wants to determine the proportion of households in the district that would support starting the school year a week earlier. They ask a random sample of 100 households whether they would support starting the school year a week earlier, and 43 households responded that they would.Suppose a large candy machine has 45% orange candies. Imagine taking an SRS of 25 candies from the machine and observing the sample proportion. p ^ \hat{p} p ^ of orange candies. Find the standard deviation of the sampling distribution of. p ^. \hat{p}. p ^ . Check to see if the 10% condition is met.

The company needs to sample enough customers so that they expect each mode of payment to appear at least 5 times.

The Law of Large Numbers is very simple: as the number of identically distributed, randomly generated variables increases, their sample mean (average) approaches their theoretical mean.
