Question 14 of 35 In a population of size 40 students, 5 will be randomly selected. Each student was assigned a number from 1 to 40. Suppose student with number 24 is selected then, what are the other systematic samples? Select the correct response: 3, 10, 17, 31 6, 14, 30, 38 4, 13, 21, 39 1, 10, 19, 37

We wish to gather some information relating to the average time a hospitalized Eagle Flu patient remains in the hospital. We randomly sample 16 cured formerly hospitalized Eagle Flu patients and these were the number of days spent in the hospital: 6.09, 8.04, 6.43, 8.58, 10.34, 5.40, 9.87, 9.24, 9.18, 5.06, 5.39, 5.89, 11.91, 8.94, 5.68, 9.85Many surveys of flu hospital stays show that hospitalization length is normally distributed. So, we assume that our sample comes from a normal population with unknown mean of μ days and an unknown standard deviation of σ days. We would like to test whether the average hospital stay length is less than 8.1 days..The null hypothesis is thus H0:μ=8.1 . We will test this against the alternative Ha We want to test at the 8% level.Let x = the sample mean and s = the sample standard deviation.f) Calculate the critical value, tstar, for your test.(negative value)

Suppose you are the president of the student government. You wish to conduct a survey to determine the student body's opinion regarding student services. The administration provides you with a list of the names and phone numbers of 5,412 registered student. Discuss the procedure you would follow to obtain a systematic random sample of 100 students.

In a study with 5 groups, 6 samples each group, what are the degrees of freedom for the total, group, and error, respectively? a. 29, 5, 25 b. 29, 25, 4 c. 29, 5, 24 d. 29, 4, 25

In selecting a sample, if you were to obtain a systematic sample of 40 from a population of 600, and your randomly selected starting point is 12, your next three selections should be: a. 24, 36, 48  b. 27, 42, 57  c. 42,92, 137  d. 90, 140, 190

Consider the population consisting of {4,5,9}. If samples of size n = 2 are randomly selected from the population with replacement compute the mean of the sample medians Multiple choice answers  5 6 7 4 5.5

table 1 gives flight arrival numbers from a random sample of flights for airlines.  Airline 1  early =133  on-time = 416+ late =150 total 699..  Airline 2 early =58  on-time =354 late =87 total =499.  total early = 191  on-time =770  late =237  overall total =1198 . Test whether there is a difference between the two airlines in the percent of flights that arrive late.                                                                                        FIND THE RELEVANT SAMPLE PROPORTIONS IN EACH GROUP AND THE POOLED PROPORTION.                                                                    P HAT 1=  ?

2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:

Consider the following random sample of data: -7, 5, -1, -1, 8, 1, 7, -4, 8, 80 a) What is the mean of the sample data? Round your response to at least 2 decimal places. Number b) If the outlier is removed, what is the mean of the remaining sample data? Round your response to at least 2 decimal places. Number

Imagine a researcher asks a sample of five people to drive two types of cars and rate each of them on a scale of 1 to 25. The researcher wants to know: Is there is a difference in the ratings of the two types of cars. Below are the data collected: Type A: 20, 10, 11, 23, 7 Type B: 10, 11, 4, 12, 1 what type of T Test would be appropriate
