uestionQ2. Borneo Steel Corporation produces iron rings that are supplied to ARAAB Co. Ltd.These rings are supposed to have a diameter of 60 cm. The machine that makes theserings does not produce each ring with diameter of exactly 60 cm. The diameter of each ofthe rings varies slightly. It is known that when the machine is working properly, the ringsmade on this machine have a mean diameter of 60 cm. The quality control departmenttakes a random sample of 35 such rings every week, calculates the mean of the diametersfor these rings and makes a 99% confidence interval for the population mean. If eitherthe lower limit of this confidence interval is less than 59.938 cm or the upper limit of thisconfidence interval is greater than 60.063 cm, the machine is stopped and adjusted. Arecent sample of 35 rings produced a mean diameter of 60.038 cm with a standarddeviation of 0.15 cm. Based on this sample can you conclude that the machine needs anadjustment?

A popular news magazine wants to write an article on how much Americans know about geography. They devise a test that lists 100 cities in the US, all of them mentioned in the news magazine in the last year. Each respondent must guess the state in which the city can be found. Some examples were: (Los Angeles, Tuscon, Biloxi.) Each correct answer earns one point. Assume the scores have normal distribution with mean 62 and standard deviation 12. What is the probability of scores are between 50 and 74 points?
A survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements? Click to view page 1 of the table. Click to view page 2 of the table. ... a. The percentage of women who meet the height requirement is %. (Round to two decimal places as needed.) Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? A.

After the measles outbreak, the barangay captain of Big Rock wanted to assess the satisfaction of the residents to his actions during the outbreak. He then obtained a random sample of 5 residents per block (Block 1 to Block 5) and asked them their satisfaction (1 - very dissatisfied, 2 - dissatisfied, 3 - satisfied, 4 - very satisfied). He wanted to know if the satisfaction of his residents differ from across blocks. 1. TRUE OR FALSE: We should test the normality of responses per blocks before we proceed with the test of hypothesis on comparing these responses across blocks. 2. The appropriate alternative hypothesis to compare satisfaction of residents across blocks is ____. ( See image for choices) 3. The appropriate test procedure to test the hypothesis is ___. A. T-test B. Z-test C. F-test using ANOVA D. Kruskal-Wallis Test E. None of the above
