According to a report of the National Foundation for Infectious
Diseases 46% of all college students in the US receive the flu
vaccine.
Suppose that 6 college students are selected at random.
Let X = the number of college students who are vaccinated in a
random sample of 6 college students.
Suppose you are asked to produce a stick graph representing the distribution of X. How many sticks will be included in your stick graph?
- What is the distribution of X? Be specific: Provide the name of the distribution and the values of the appropriate parameters.
- What is the expected value of X? What is the standard deviation of X? For each of the numerical summaries, provide the symbol, value, and units.
- List all the values of X that are within one standard deviation of the mean.
Be sure to clearly label your answer as part 1, part 2, part 3
After reading the report released by the National Foundation for
Infectious Diseases, you find it hard to believe that only 46% of
college students get the flu vaccine, after all, the colleges and
universities are constantly offering incentives such as free food,
gift cards, etc.
You decide to conduct a brief survey. In a random sample of 30
students, all 30 said that they got the flu
vaccine. Do the results of your study make you
doubt the value of 46% reported by the National Foundation for
Infectious Diseases?
Provide a written response to address this question and include
appropriate numerical support.

According to the report by the government-lending institution, college students who have credit cards have an average credit card balance of $1,086. A random sample of 60 college students was selected, and their average credit card debt was found to be $1,440. Assume the standard deviation for student credit card debt is $286. Using a = 0.10, complete parts a and b below. a. Does this sample provide enough evidence to challenge the findings by the lending institution? Determine the...

According to a money report by a government institution, 18-to-20-year-old college students have an average credit card balance of $569. A researcher wants to find out if this number is lower now and collects data for a random sample of 40 college students. Their average credit card debt was found to be $542 with a sample standard deviation of $67.21. Complete parts a through b. a.) Using alphaα=.05, does this sample provide enough evidence to conclude that the average credit...

A random sample of 46 college students reported the number of hours per day they typically spend on social media. Their sample mean is, M = 2.61, and their standard deviation is, s = 1.02. If you plan to construct a 95% confidence interval for the population mean, what t critical value should you use based on this data?

Total sleep time of college students. A recent survey describes the distribution of total sleep time among college students as approximately Normal with a mean of 6.78 hours and standard deviation of 1.24 hours.3 Suppose that we select a college student at random and obtain his or her sleep time. This result is a random variable X because, prior to the random sampling, we don't know the sleep time. We do know, however, that in repeated sampling, X will have...

Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate the mean score u of those who took the MCAT on your campus, you will obtain the scores of an SRS of students. The scores follow a Normal distribution, and from published information you know that the standard deviation is 10.8. Suppose that, unknown to you, the mean score of those taking the MCAT on your campus is 495. In...
