Conditions for Inference about a Population Mean. Random Sample - The data are a random sample from the population of interest. 10% Rule - The sample size is no more than 10% of the population size: ≤. 10. Large Counts/Normality – If the sample size is large ( ≥ 30), then we can assume normality for any shape of distribution.Scenario 1: The expected number of red M&M’S is 6 and we get 16 red M&M’S. Scenario 2: The expected number of red M&M’S is 500 and we get 510 M&M’S. Which scenario provides more convincing evidence against the company’s claim? In both scenarios, the observed value is 10 away from the expected. But Scenario 1 provides much more ...The z-test is a statistical test for comparing the proportions from two populations. It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))Bias refers to a systematic deviation from the true value or an unfair influence that affects the results of statistical analysis. It can occur during data collection, sampling, or analysis and leads to inaccurate or misleading conclusions. The large counts condition, also known as the "success-failure" condition, is used when applying certain ...

The large counts condition can be expressed as np ≥ 10 and n (1-p) ≥ 10, where n is the sample size and p is the sample proportion. This means that both the number of successes (np) and the number of failures (n (1-p)) in the sample should be at least 10.

State appropriate hypotheses and compute the expected counts and chi-square test statistic for a chi-square test for goodness of fit. State and check the Random, 10%, and Large Counts conditions for performing a chi-square test for goodness of fit. Calculate the degrees of freedom and P-value for a chi-square test for goodness of fit.

Large Counts: the counts of successes, failures in each sample/group are at least 10 (n1phat1, n1 (1-phat1), n2phat2, n2 (1-phat2)) How do we standardize p1-p2? 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. 🧢
