An independent survey claimed that the average number of people who will vote for BBM in Visayas is greater than the average number of people who will vote for VPLR in Luzon. To validate this survey, a group of researchers conducted a post-test.In a survey of 210 people in Luzon, the average number of people who will vote for VPLR is 153 with a population standard deviation of 7.6. In a survey of 200 people in Visayas, the average number of people who will vote for BBM is 155 with a population standard deviation of 12.6. At α = 0.05, can people trust the result of the survey?

The U.S Navy requires that fighter pilots have heights between 64 inches and 74 inches. The Men’s are normally distributed with a mean of 68.6 inches andthe standard deviation of 2.8 inches. a) Find the percentage of men meeting the height requirement b) If the Air Force height requirements are changed to exclude only the tallest 4% and the shortest 4% of men, what are the new height requirements?
An ordinary traveler claims that the average difference between the plane fares of all trips from the Philippines to a certain destination in the two airlines is significantly different. To validate this claim, 145 trips have been randomly selected from the first airline, which gave a mean fare of PHP 23,502.71 with a sample standard deviation of PHP 4,853.39. On the other hand, 123 trips are chosen at random from the second airline, which provided a mean fare of PHP 21,884.09 with a sample standard deviation of PHP 4,987.73. Assume that the populations are normally distributed, and the standard deviations for both populations are equal. At ? = 0.01, indicate whether or not there is sufficient evidence to support the traveler’s claim
The mean attention span for a ten-year-old in the USA is 19.10 minutes with a standard deviation of 2.03 minutes. Dr. Nintendoaddict think that video game playing may increase attention span. Dr. Nintendoaddict surveys 25 ten-year-olds who regularly play video games and measure their attention span. Dr Nintendoaddict find that the video game players’ mean attention span is 20.85 minutes with a standard deviation of 2.45 minutes. What is the critical value of z for alpha = .05?
According to a leasing firm's reports, the mean number of miles driven annually in its leased cars is 13,480 miles with a standard deviation of 1240 miles. The company recently starting using new contracts which require customers to have the cars serviced at their own expense. The company's owner believes the mean number of miles driven annually under the new contracts, H, is less than 13,480 miles. He takes a random sample of 80 cars under the new contracts. The cars in the sample had a mean of L3,280 annual miles driven. Is there support for the claim, at the 0.01 level of significance, that the population mean number of miles driven annually by cars under the new contracts, is less than 13,480 miles? Assume that the population standard deviation of miles driven annually was not affected by the change to the contracts. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified…
At EM Industries a certain machine fills 2-pound (32 ounces) boxes with cereal. The machine’s actual fill amount for the 2-pound box is found to have an average of 31.9 ounces and standard deviation of 0.40 ounces. If a box has at least 31.5 ounces of cereal, it considered “acceptable” by the government office of food product regulation. If a box has more than 32.5 ounces of cereal, it is considered “over-filled” by operations managers at EM Industries. a) What is the probability that a randomly filled box is “acceptable”? What is the probability that a randomly selected box is both, at the same time, “acceptable” and NOT “over-filled”? b) To monitor the current performance of the box filling process, Mo Nerdstat, quality control manager, decides to measure 20 boxes an hour and track this average performance measure over time. Develop 3-sigma limits for the current average process and draw the associated averages control chart.
A private college in Ohio wishes to determine whether or not students living on campus have similar GPA’s to commuter students. They survey 120 resident students and find an average GPA of 2.82, with a sample standard deviation of .71. They also survey 90 commuter students and find an average GPA of 2.65, with a sample standard deviation of .58. Test the claim that resident students and commuter students have the same average GPA, against the alternative that these GPA’s differ, using a = .02.
A study was made to determine if the subject matter in a physics course is better understood when a lab constitutes part of the course. Students were randomly selected to participate in either a 3-semester hour course without labs or a 4-semester-hour course with labs. In the section with labs, 11 students made an average grade of 85 with a standard deviation of 4.7, and in the section without labs, 17 students made an average grade of 79 with a standard deviation of 6.1. Would you say that the laboratory course increases the average grade by as much as 8 points? Use 0.05 level of SIgnificance.
