The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was χ2=7.82 with a corresponding p-value of 0.02.

what are the 3 things checked under plan? 1. state: We want to estimate p = the true proportion of _____. 2. plan: if the conditions are met, we will construct a one-sample t/z interval for p. - random, 10%, large counts. 3. do (use formula for one-sample t or z) 4. conclude: confidence interval interpretation.When calculating critical values from Table A, students will mistakenly look for the wrong area. For example, when finding the critical value for an 80% confidence interval, naturally students want to look for an area of 0.80. But we know that Table A gives the area to the left of a specific z-score, which includes the 10% area in the left tail.What is the smallest sample size Miriam can take to pass the large counts condition?

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.

Chi-squared tests require two familiar conditions for inference: When sampling without replacement, we should check the 10% condition for independence (n < 10%N) For our large counts condition, we need to verify that all of our expected counts are at least 5 (similar to other chi-square test set-ups). 🗼.Success/Failure Condition: There should be at least 10 expected successes and 10 expected failures in a sample in order to use the normal distribution as an approximation. Written using notation, we must verify both of the following: Expected number of successes is at least 10: np ≥ 10. Expected number of failures is at least 10: n (1-p) ≥ 10. aeires auhsd In general, the Large Enough Sample Condition applies if any of these conditions are true: You have a symmetric distribution or unimodal distribution without outliers: a sample size of 15 is “large enough.”.
