The director of the IRS has been flooded with complaints that people must wait more than 55 minutes before seeing an IRS representative. To determine the validity ofthese complaints, the IRS randomly selects 400 people entering IRS offices across the country and records the times which they must wait before seeing an IRSrepresentative. The average waiting time for the sample is 57 minutes with a standard deviation of 3 minutes. Is there overwhelming evidence to support the claim thatthe wait time to see an IRS representative is more than 55 minutes at a 0.005 significance level?Step 3 of 3: Choose the best option below that describes the statistical and practical significance of this test.AnswerTablesAlthough the test was not statistically significant, there is a practical difference between a wait time of 55 minutes and 57 minutes.○ The test was neither statistically nor practically significant.○ The test was both statistically and practically significant.Although the test was statistically significant, there is no practical difference between a wait time of 55 minutes and 57 minutes.KeypadKeyboard Shortcuts

What is the standard deviation (sd) of the number of cardinal birds observed?
According to a news program, Americans take an average of 4.9 days off per year because of illness. The manager of a large chain of grocery stores wants to know if the employees at the grocery store, on average, take fewer days off than the national average. The manager selects a random sample of 80 employees in the company and found the sample mean number of days off for the 80 employees was 4.75 days with a standard deviation of 0.9 days. When the manager performed a significance test, the P-value was 0.07. What is the meaning of this P-value in context?
A company conducted a survey on the number of hours employees spend on a particular task per week. The data collected from a sample of 10 employees are as follows: 5, 6, 7, 8, 9, 10, 10, 11, 12, 13. Calculate the standard deviation of the hours spent on the task per week.
Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 42 randomly selected people who train in groups and finds that they run a mean of 47.1 miles per week. Assume that the population standard deviation for group runners is known to be 4.4 miles per week. She also interviews a random sample of 47 people who train on their own and finds that they run a mean of 48.5 miles per week. Assume that the population standard deviation for people who run by themselves is 1.8 miles per week. Test the claim at the 0.01 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 2.3 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? O A. Yes, because the percentage of women who meet the height requirement is fairly large. OB. No, because the percentage of women who meet the height…
Fuel efficiency of Prius: Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. (a) The EPA claims that a 2012 Prius gets 50 MPG (city and highway mileage combined). Do these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov? The test statistic is: __________________(please round to two decimal places)The p-value:___________________________ for this hypothesis test is: (please round to four decimal places)(c) Please comment on the primary thing that is wrong about the following statement: There is sufficient evidence…
The weight of a standard poodle is 50 pounds with a standard deviation of 15 pounds. If a poodle is underweight, they can have some very serious health issues, so it is important to get them seen by a vet if they are underweight. If a vet suspects that they are underweight, they will put them on a special food diet that will help them gain weight. A veterinarian medicine researcher has developed a new weight gain diet food and is conducting a completely randomized design. She puts 12 underweight poodles in the treatment group and 12 underweight poodles in the control group. The treatment group gets the new weight gain diet food while the control group gets the current weight gain diet food. At the end of the study, the weight gain in the treatment group was 12 pounds with a standard deviation of 3 pounds, and the weight gain in the control group was 8 pounds with a standard deviation of 3.5 pounds. Which of the following intervals successfully captures the p-value? (A) Below 0.01 (B)…
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?
The honors program at Brad's university only accepts students with an entrance exam score over 400. What percentage of students would be eligible if the students at Brad's school have an average exam score of 250, with a standard deviation of 80?
A researcher wants to determine the average height of students in a university using convenience sampling. They measure the height of 15 students selected based on their availability and accessibility. The mean height of these students is 170 cm with a standard deviation of 5 cm. Can the researcher use this sample to make inferences about the population of all students at the university?
The administrator at your local hospital states that on weekends the average wait time for emergency room visits is 10 minutes. Based on discussions you have had with friends who have complained on how long they waited to be seen in the ER over a weekend, you dispute the administrator’s claim. You decide to test your hypothesis. Over the course of a few weekends, you record the wait time for 40 randomly selected patients. The average wait time for these 40 patients is 11 minutes with a standard deviation of 3 minutes. Do you have enough evidence to support your hypothesis that the average ER wait time is different than 10 minutes? You opt to conduct the test at an α = 0.025 level of significance.
A survey found that women's heights are normally distributed with mean 63.96 in and standard deviation 2.2 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?
