Station 1 and 2 are located near the plants discharge tubes while Station 3is located farther out in the bay.

According to the National Institute on Alcohol Abuse and Alcoholism, and the National Institutes of Health, 41% of college students nationwide engage in binge drinking behavior, having five or more drinks on one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drink is lower than the national proportion. In a commissioned study, 629 students are selected randomly from a list of all students enrolled at the college. Of these, 241 admitted to having engaged in binge drinking. The college president is more interested in testing her suspicion that the proportion of students at her college that binge drink is lower than the national proportion of 0.41. Her staff tests the hypotheses H0: p = 0.41, Ha: p < 0.41. What is the value of the test statistic? Select one: a. -1.37 b. –2.59 c. –1.58 d. 0.3506

A college president wonders if the proportion of students enrolled at her college that binge drinks is lower than the national proportion. In a commissioned study, 462 students are selected randomly from a list of all students enrolled at the college. Of these, 166 admitted to having engaged in binge drinking. The college president is more interested in testing her suspicion that the proportion of students at her college that binge drinks is lower than the national proportion of 0.41. Her staff tests the hypotheses H0: p = 0.41, Ha: p < 0.41. The P-value is: Select one: below 0.01. between 0.05 and 0.1. between 0.025 and 0.05. between 0.01 and 0.025.
The Environmental Protection Agency is considering inspecting 6 plants for environmentalcompliance: 3 in Chicago, 2 in Los Angeles, and 1 in New York. Due to a lack of inspectors,they decide to inspect two plants selected at random, one this month and one next month, with each plant equally likely to be selected, but no plant selected twice. What is the prob-ability that 1 Chicago plant and 1 Los Angeles plant are selected?
Some researchers have conjectured that stem-pitting disease in peach-tree seedlings might be controlled with weed and soil treatment. An experiment is conducted to compare peach-tree seedling growth when the soil and weeds are treated with one of two herbicides. In a field containing 20 seedlings, 10 are randomly selected throughout the field and assigned to receive Herbicide A. The remainder of the seedlings is assigned to receive Herbicide B. Soil and weeds for each seedling are treated with the appropriate herbicide, and at the end of the study period the height in centimeters is recorded for each seedling. The following results are obtained: Mean Std. Dev. Herbicide A 94.5 cm 10 cm Herbicide B 109.1 cm 9 cm Reference: Ref 7-14 Suppose we wish to determine if there tends to be a difference in height for the seedlings treated with the different herbicides. Find the P-value for this test assuming the standard deviations of the two populations are equal.
A Not for profit Organization (NPO) wants to create a sample of financially backward girl students who are unable to continue their higher education, from the AL Dakhliya governorate. The organization wishes to sponsor the students’ higher education expenses. For this purpose in the first stage, the NGO randomly selects some wilayats from the 8 wilayats in the Al Dakhliya governorate to form a sample and then selects all girl students from the selected wilayats to extend help to them by providing sponsorship for their higher education. Which among the following statement is true about the sampling method chosen here? a. This method is based on the judgement of the researcher b. It is a probability sampling method c. It is a non- probability sampling method d. This method is also known as judgement sampling

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institutes of Health (NIH), 41% of college students nationwide engage in "binge-drinking" behavior: having five or more drinks on one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college who binge drink is actually lower than the national proportion. In a commissioned study, 344 students are selected randomly from a list of all students enrolled at the college. Of these, 132 admit to having engaged in binge drinking.The college president is more interested in testing her belief that the proportion of students at her college who engage in binge drinking is lower than the national proportion of 0.41. What is the P-value? (Round your answer to four decimal places.)P-value = ?
Researchers constructed two test sheets, each sheet including 20 photos of the faces of dog–owner pairs taken at a dog lovers' field festival. The 20 sets of dog–owner pairs on the two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet, the dogs were matched with their owners, while on the second sheet, the dogs and owners were deliberately mismatched. Three experiments were conducted, and in all experiments, subjects were asked to "choose the set of dog–owner pairs that resemble each other, Sheet 1 or Sheet 2," and were simply told the aim of the research was a "survey on dog–owner relationships." In the first experiment, the original sheets were shown to subjects; in the second experiment, just the "mouth region" of the owners was blacked out in all the pictures on both sheets; in the third experiment, just the "eye region" of the owners was blacked out. Subjects were assigned at random to the three experimental groups, and…

A survey showed that 37% of human resource professionals are at companies that rejected job candidates because of information found on their social media. If 25 human resource professionals are randomly selected, would 14 be a significantly high number to be at companies that rejected job candidates because of information found on their social media? Why or why not?
Due to the rising costs of accidents, many employers have started requring employees to take courses designed to heighten safety awareness. One company is trying to decide which one of the two courses to implement. To helo make a decision, ten employees selected at random to take course A, and another ten randomly selescted employees take course b. Each employee then takes the same safety test that is graded out of a possible 50 points. Based on the safety test scores, the comapny conccluded that neither course was significantly better at heightening safety awareness. The response variable for this study is: A) safety awareness B)20 employees C)The safety test score D Course A and Course B
There are four blood types, and not all are equally likely to be in blood banks. Records in a local blood bank show that, historically, 49% of donations are type O blood, 27% are type A blood, 20% are type B blood, and 4% are type AB blood. The blood bank takes a random sample of 40 donations from the past month, and finds that 25 were type O, 10 were type A, 4 were type B, and 1 was type AB. The blood bank would like to determine if the distribution of blood types in the past month’s sample is significantly different from the historical distribution of blood types. What are the hypotheses the blood bank should use? A. H0: In this month, the distribution of blood types matches the historical distribution of blood types.Ha: In this month, none of the blood type proportions match the corresponding historical proportions. B. H0: In this month, the distribution of blood types does not match the historical distribution of blood types.Ha: In this month, at least one of the blood type…
