Please scroll down to see the entire question. The quality control manager of an automobile parts factory would like to know whether there is a difference between the proportion of defective parts produced on different days of the work week. Random samples of 100 parts produced on each day of the week were selected, with the following results: Result: Mon Tues Wed Thurs Fri # of defective parts: 12 7 7 10 14 # of non-defective parts: 88 93 93 90 86 At 5% level of significance, is there evidence of a significant difference in the proportion of defective parts produced on the various days of the week (A ) Step-1: State the hypotheses ( H0 and H1 ), and identify the claim A. H0: Proportion of defective parts is not the same for the days of the week. H1: Proportion of defective parts is the same for all days of the week B. H0: Proportion of defective parts is dependent on the days of the week H1: Proportionof defective parts is…

dults aged 18 years old and older were randomly selected for a survey on obesity. Adults are considered obese if their body mass index (BMI) is at least 30. The researchers wanted to determine if the proportion of southern women who are obese is less than the proportion of southern men who are obese. The results are shown in the table below. Test at the 1% level of significance. Number who are obese Sample size Men 42,773 155,525 Women 67,176 248,775 a.State the distribution to use for the test. (Round your answers to five decimal places. b. What is the test statistic c. Conduct a Hypothesis Test
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 39% with a margin of error of 1.3%. Describe the conclusion about p using an absolute value inequality. The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to ≤ . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to ≥. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).

advocacy organization surveys 966 citizens of country A and 186 of them reported being born in another country. Similarly, 177 out of 1213 citizens of country B reported being foreign-born. The researchers want to test if the proportions of foreign born are the e in country B as in country A. Complete parts a through c below. What is the difference in the sample proportions, p, - p2, of foreign born residents from both countries? Assume p, is the proportion of foreign born residents from country A and p, is the proportion of foreign born residents from country B. difference in the sample proportions, p1-P2, is und to three decimal places as needed )
