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? What is the X variable in this case? What is the null hypothesis statement? What is the alternative hypothesis statement?

According to a government agency, the average workweek for an adult in February 2018 was 34.1 hours. Assume the population standard deviation for the number of hours worked per week is 4.0 hours. A random sample of 35 adults worked an average of 34.8 hours last week.
A USA based cable broadband company wants to investigate whether it's east coasts customers have a higher average customer satisfaction score than compared to it's west coast customers. The customer survey asks for a score between 1 and 5, with 1 being poor and 5 being excellent. 174 east coast customers are surveyed, and the sample mean is 3.35 with a sample standard deviation of 0.51. For the west coast, 355 customers are surveyed, and the sample mean is 3.24 with a sample standard deviation of 0.52.
A researcher claims that the stomachs of blue crabs from Location A contain more fish than the stomachs of blue crabs from Location B. The stomach contents of a sample of 14 blue crabs from Location A contain a mean of 194 milligrams of fish and a standard deviation of 37 milligrams. The stomach contents of a sample of 8 blue crabs from Location B contain a mean of 184 milligrams of fish and a standard deviation of 44 milligrams. At a = 0.05, can you support the researcher's claim? Assume the population variances are equal. Complete parts (a) through (d) below. (a) Identify the null and alternative hypotheses. Choose the correct answer below. ОА. Но H1-H2 0 OD. Ho: H₁-12₂=0 Ha H1 H₂0 enough evidence at the 5% level of significance to support the researcher's claim.
A medical journal published the results of a study to compare the effectiveness of handwashing with soap and handrubbing with alcohol. Health care workers who used handrubbing had a mean bacterial count of 34 per hand with a standard deviation of 65. Health care workers who used handwashing had a mean bacterial count of 67 per hand with a standard deviation of 103. In a random sample of 50 health care workers, all using the same method of cleaning their hands, the mean bacterial count per hand, x, is less than 33. Give your opinion on whether this sample of workers used handrubbing with alcohol or handwashing with soap. Click the icon to view the table of normal curve areas. Since the probability of x being less than 33 is alcohol, and used if this sample of workers used handrubbing with ▼if they used handwashing with soap, it is more likely that this sample of workers
An elementary school class ran 1 mile with a mean of 11 minutes and a standard deviation of 3minutes. Rachel, a student in the class, ran 1 mile in 8 minutes. A junior high school class ran 1mile with a mean of 9 minutes and a standard deviation of 2 minutes. Kenji, a student in the class,ran 1 mile in 8.5 minutes. A high school class ran 1 mile with a mean of 7 minutes and a standarddeviation of 4 minutes. Nedda, a student in the class, ran 1 mile in 8 minutes. a. Why is Kenji considered a better runner than Nedda, even though Nedda ran faster than he? b. Who is the fastest runner with respect to his or her class? Explain why
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?
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 researcher claims that the stomachs of blue crabs from Location A contain more fish than the stomachs of blue crabs from Location B.

The stomach contents of a sample of 8 blue crabs from Location B contain a mean of 189 milligrams of fish and a standard deviation of 44 milligrams. At a = 0.10, can you support the researcher's claim? Assume the population variances are equal. Complete parts (a) through (d) below. t= 0.110 (Round to three decimal places as needed.)

There are two samples. One is a group of 8 athletes who practice and the other is a group of 5 athletes who do not practice. The mean for group 1 is 92.4 and the standard deviation is 5.83. For group 2, the mean is 81.3 and the standard deviation 7.85. the coach thinks the true mean for the athletes who did not practice is more that 8 points smaller than those who did practice. a) make the null and alternative hypotheses. calculate the test statistic and give an explanation as to why you chose this test statistic.
A college admissions officer believes that students enrolling from Shawnee school District have higher SAT scores than those who enroll from West River School District. A sample of 30 students from each district is selected. The average SAT score for the group from the Shawnee district is 656 with a standard deviation of 100. The average SAT score for the group from the West River district is 560 with a standard deviation of 90. Is the belief of the admissions officer substantiated?
