In order to meet the conditions for independence and large counts for a chi-square goodness-of-fit test, which of the following represents all possible sizes of the monthly samples? E. x2 ...First of all, the conditions are met: 9 weeks is less than 10% of a decade. We can view the 9 weeks as a random sample. The population is normally distributed. 𝑧 = (35200 − 35800)∕ (720∕√9) = −2.5, which gives us the probability of a random sample mean being $35,200 or less as 𝑝 = 0.0062 < 𝛼 = 0.05,

Did you know?

The 10% Condition says that our sample size should be less than or equal to 10% of the population size in order to safely make the assumption that a set of Bernoulli trials is independent. Of course, it's best if our sample size is much less than 10% of the population size so that our inferences about the population are as accurate as possible.Random Condition: so we can generalize to the population. 10% Condition: so sampling without replacement is OK. Large Counts/Normal Condition: so the sampling distribution of the sample proportions will be approximately Normal and we can use z to find a P-value.

The chi-square statistic is a meaure of how far the observed counts are from the expected counts. The formula is x^2= sum of (observed-expected)^2/expected.

So our large counts condition would change to 0.55(85) ≥ 10 & 0.45(85) ≥ 10, which still holds for this particular problem. In other words, when we are given an actual p to check this condition, use it. When we aren't given a p-value, use the next best thing by using your p-hat. 🧢 The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ...

For first sample, number of success and failures is not at least. Success = 16 > 10. and. failure = 25 - 16 = 9 < 10 (condition failed) Therefore, we cannot use the method because the condition of large count or success failure is not satisfied.

50 (0.6)=30. Now look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30.

The Large Counts Condition is satisfied when both np and n (1-p) are greater than or equal to 10, where n is the sample size and p is the probability of success. In other words, if the number of successes and failures in the sample is large enough, then we can assume that the distribution of the count of successes follows a normal distribution.Jan 15, 2020 ...
