ALTERNATE EXAMPLE (page 392)More Hoop FeverInsbasteSD of a sum or difference of random variablesPROBLEM:ATAMAIn Hoop Fever, a player has 60 seconds to make as many baskets as possible. Morgan andTim play head-to-head every Tuesday. Let M = the number of baskets made by Morgan andT = the number of baskets made by Tim in a randomly selected match. Based on previous%3Dmatches, we know that oM = 5.7 and oT = 10.3. Assume that these two random variables areindependent. Define D = M – T. Earlier, we found that uD = 8.6. Calculate and interpret the%3Dstandard deviation of D.ebdon ng w

Introduction: The random variable M is the number of baskets made by Person M, and the random…

In the experiment of rolling two dice, what is the probability that the differencebetween the largest and the least values is 1 or 5?
Subject:statistics
A die is rolled. If an odd number turns up, we win an amount equal to this number; if an even number turns up, we lose an amount equal to this number. For example, if a two turns up we lose 2, and if a three comes up we win 3. What is the average profit you can make if you participate this game?

Scenario: What influences the likelihood of whether a person will assist a stranger? In this study, participants were shown four conditions and asked to provide the percent likelihood that they would be willing to help in each condition. The researcher wanted to see if likelihood of helping varies based on the number of bystanders (0 or 10), and/or the gender of the stranger (male or female). Each participant participated in all four conditions (0 bystanders with a female; 0 bystanders with a male; 10 bystanders with a female; 10 bystanders with a male). Question: As taught in 510/515, what is the most appropriate graph if the only significant finding in this scenario is the main effect of number of bystanders? Group of answer choices Histogram Scatterplot Bar graph Box plot Line graph
In small town there are three different types of whether conditions: sunny day, rainy day, and windy day. A sunny day never happens two days in a row. If it is a sunny day, it is as likely to have a rainy day or windy day the next day. If it is a windy day or rainy day, it has an even chance of having the same conditions next day. For the other 50%, it is two times more likely to have a bad weather conditions than a sunny day. a) (Calculate without using matrix multiplication, hint: calculate just the needed value or matrix element)? b) What is the probability of having sunny 4 days from now, if today is a rainy day? c) What is the probability of having a rainy day 3 days from now if today is a windy day? d) Obtain the mean first passage time for all states

The first test a doctor would order to determine whether a person is infected with HIV (the virus that causes AIDS) is the ELISA test. It detects antibodies and antigens for HIV. A study in Statistical Science by J. Gastwirth estimated that, if the person is actually infected with HIV, this test produces a positive result 97.7% of the time. If a person is not infected with HIV, the test result is negative 92.6% of the time. According the the US Centers for Disease Control (CDC), an estimated 1.1 million Americans out of a population of 321 million were infected with HIV in 2015. Using the information above, determine the probability that a randomly selected person whose ELISA test is positive actually is infected with HIV? a. What is the probability that a randomly selected American is infected with HIV? b. Using the answer to part (a) and the conditional probabilities of positive and negative ELISA test results, fill out the contingency table below: ELISA Test Result…
