The average age of students at the University of Houston – Downtown is about 28 years old. The president of the university believes that the age of full-time students attending classes during the day is lower that the average of all students. Test this hypothesis. Be sure to show all five steps.

We're interested in whether there's a relationship between the Visual and ReadWrite learning styles of Biology students. We know that the standard deviation of Visual scores for the students in our classroom is 3.231746, the standard deviation for the ReadWrite scores is 3.578245, and the covariance between these two variables is 3.747628. Calculate the Pearson product-moment correlation coefficient for these two variables, based on these numbers:

0.3241

Question 36 Calculate the t-statistic associated with the null hypothesis that there is no correlation between the VARK Visual and VARK ReadWrite scores:

Suppose that student scores on math skills test are normally distributed. The mean of the test is 35 and the standard deviation is 4. Using a z-table (normal curve table), what percentage of students have z-scores a) below 2.05 b) above -0.50 Using a z-table, what scores would be the top and bottom score to find the c) middle 15% of students d) middle 25% of students Using a z-table, what is the minimum raw score a student can have on the math skills test and be in the bottom e) 25% f) 5%

Suppose that student scores on creativity test are normally distributed. The mean of the test is 150 and the standard deviation is 23. Using a z-table (normal curve table), what percentage of students have z-scores a) below 1.63 b) above -0.41 Using a z-table, what scores would be the top and bottom raw score to find the c) middle 50% of students d) middle 10% of students Using a z-table, what is the minimum raw score a student can have on the creativity test and be in the top e) 35% f) 15%

Cheap-As-Dirt Rental Company advertises that the average cost of a rental they find for undergraduate students at the University of Oregon is $580 with a standard deviation of $75 (Let us assume the rents are approximately Normally distributed.) The Department of Consumer Protection will investigate the company if, when they choose a sample of students, they find that the average rental cost for those students is $610 or more. Assuming that the company is advertising truthfully, what is the probability that the company will be investigated if the Department of Consumer Protection samples 8 clients? (Round your answer to 4 decimal places, to the ten thousandths place.)vg

In a nursing program, 85% of incoming freshmen nursing students are female while 15% are male.  Recent records indicate that 70% of the entering female students will graduate with a BSN degree, while 90% of the male students will obtain a BSN degree.

Suppose an incoming freshman nursing student is chosen at random. Use a tree diagram or probability formula to find the following.

a. Find the probability the student is female and graduates with a BSN degree.

b. Find the probability the student graduates with a BSN degree.

c. Find the probability the student is a female given that the student graduates with a BSN degree.

1. The reading speed of second grade students is approximately normal with a mean of 86 words per minute and a standard deviation of 12 words per minute.

a) What is the probability that a randomly selected student will read more than 95 words per minute?

b) What is the probability that a random sample of 12 second grade students results in a mean reading rate of more than 98 words per minute?

c) There is a 5% chance that the mean reading speed of a random sample of 20 second grade students will exceed what value?

After a long semester professor decides to organize true/false quiz for his students. The questions of this professor are infinitely difficult so for each question the students just randomly guess the answers (True and False) with equal probability 1/2. There are two options: a) a test with 4 questions where you need to write at least 3 correct answers to pass the test and b) a test with 8 questions where you need to write at least 5 correct answers to pass the test. Which quiz should the students choose to have better chances to pass?

Please remember to choose the ethical provision you believe would address the issue and remember your citations. A group of senior students have been attending nursing school together since the beginning and are friends with one another on social media. After a particularly tough day at clinical, one of the students begins to rant about the instructor, the clinical site, and the dreadful patient assignment the student had. The student even names the nurse assigned to the patient and the name of the hospital. What should the fellow students do who are classmates and on this social media site with this student?
