3.8.10The northern lights (or Aurora Borealis) appear on some nights during the winter in Alaska. The nights on which they appear occur at random. The website for ahotel you are planning to visit in Alaska shows that the northern lights have appeared 593 nights over the past 210 winter weeks.Suppose that you randomly pick a week next winter to visit. What are the mean and standard deviation of the number of nights the northern lights appear theweek you visit? To answer, use the data shown on the hotel's website and assume that the number of nights the northern lights appear follows a Poissondistribution. Round your answers to two decimal places.(a) mean:(b) standard deviation:|

See picture for questions a and b. Problem For admission to graduate school, Diane is taking the physics subject-matter test, and Lena is taking the chemistry subject-matter test. For each of these tests, the distribution of scores is clearly bell-shaped. Scores for the physics test have a population mean of 631 points with a standard deviation of 26 points. Scores for the chemistry test have a population mean of 608 points with a standard deviation of 35 points. Diane scored 695 on the physics test, and Lena scored 667 on the chemistry test.

PLS. Solve Quickly Applications Problems According to a Sallie Mae survey and credit bureau data, in 2008, college students carried an average of $3173 debt on their credit cards (USA TODAY, April 13, 2009). Suppose that cur- rent credit card debts for all college students have a normal distribution with a mean of $3173 and a standard deviation of $800. Find the probability that credit card debt for a randomly se- lected college student is between $2109 and $3605.

Please do 12-15 and explain every step so I can understand the process.
I’ve already posted this one, but I’m posting it again, because I need to be shown what to input into my TI-84 Plus calculator to solve.
There are two national college-entrance examinations, the scholastic aptitude test (SAT) and the American College Testing program (ACT). Scores on the SATs are approximately normal with mean 500 and standard deviation 100. Scores on the ACTs are approximately normal with mean 18 and standard deviation 6. Use the links provided for the Normal (Links to an external site.)calculator and the Inverse Normal (Links to an external site.) calculator to help complete the problems, you do not need to do any work out by hand. (instructions on how to use these calculators can be found in the week 5 star on the home page) a) What percent of all SAT scores are above 600? b) Which is the greater accomplishment, scoring 630 on the SAT or 22 on the ACT ? Explain your reasoning for your choice. c) How high a score in the SAT is needed to place in the top 2.5%.
A distribution of numbers is given by the following frequency histogram. Which of the following would be true? a. The mean would be greater than the median O b. The median would be greater than the mean C. The standard deviation would be less than 1 O d. The mean would be greater than the standard deviation
See picture for question. Explaination: Eureka is a weather station in the state of California and Essex is a weather station in the state of Massachusetts. On one summer day, the noontime temperatures recorded among weather stations in California had a population mean of 29.9° Celsius and a standard deviation of 1.1° Celsius. On that same day, the noontime temperatures among weather stations in Massachusetts had a population mean of 39.2° Celsius and a standard deviation of 4.4° Celsius. On the summer day, each state's distribution of noontime temperatures among its weather stations was clearly bell-shaped. At the Eureka weather station, the noontime temperature on the summer day was 27° Celsius, and the noontime temperature at Essex was 24° Celsius.
Suppose there are 5 students in a room. The mean age is 19.8 years, and the median age is 19. If the youngest person leaves and is not replaced by another person, what happens to the mean and the median? O The mean and median increase. The mean increases, and the median either increases or stays the same. The mean increases, but it is impossible to determine whether the median increases, decreases, or stays the same. The mean increases, and the median stays the same. The median increases, and the mean either increases or stays the same.
Direction: Solve the following problems. Identify the given and provide the correct illustrations for each situation. Problem: The IQ of 100 STEM students in ZNHS are found out to be normally distributed, having a mean of 110 and a standard deviation of 10. a. If a scholarship is offered to students with IQ higher than 115, What is the percentage of qualified STEM students. b. if University of the Philippines requires at least an IQ of 100 for admission, how many of STEM students may be admitted? c. If University of the Philippines gives scholarship to the top 10% of the group, find the least IQ a ŠTEM student must have to avail scholarship.
