According to a magazine, people read an average of more than three books in a month. A survey of 30 random individuals found that the mean number of books they read was 3.2 with a standard deviation of 1.25. a. To test the magazine's claim, what should the appropriate hypotheses be? b. Compute the test statistic. c. Using a level of significance of 0.05, what is the critical value? d. Find the p-value for the test. e. What is your...

Suppose you flip three fair, mutually independent coins. Define the following events: Let A be the event that the first coin is heads. Let B be the event that the second coin is heads. Let C be the event that the third coin is heads. Let D be the event that an even number of coins are heads. Determine the probability space for this experiment (build the probability tree). Using the probability tree, find the probability of each of the...
Two, 9-sided, fair die are tossed, and the uppermost face of each die is observed. The following events are defined from this random experiment: Let...A : represent the event the uppermost faces sum to fourB : represent the event that the absolute difference between the uppermost faces is 2. For example, |die1-die2|=2C : represent the event that the product of the uppermost faces is four. For example, die1*die2 =4What is the probability that the top sides of these two dice:Part...
A bicycle company makes two mountain bike models that each come in three colors. Use the following table, which shows the production volumes for one week, to answer parts a through d. Model XK-50 FL-99 Color Blue Brown 290 90 38 207 White 191 127 a. Based on the relative frequency assessment method, what is the probability that a manufactured item is brown? P(brown) = (Round to four decimal places as needed.) b. What is the probability that the product...

please write clearly MAT150-Introduction to Statistics Writing Assignment # 3 Topic: Probability Write a brief essay in which you summarize the main points Please include formulas if needed. Discuss the concepts of mutually exclusive events and independent events. List several examples of each type of event from everyday life You need to answer only two questions. One of them must be the first question. Then you can choose between the second or third question. 1. If A andB are mutually...
2. Consider tossing a coin twice. Denote H ="head" and T ="tail" (a) List all outcomes in the sample space S (b) Let X count the number of heads. List all outcomes in the events Ao = {X = 0}, Ai = {X=1 and A2 {X = 2}. Are all the events Ao,A1,A2 mutually exclusive? Explain. (c) Suppose P(H) = 0.6. Find the probability mass function of X: f(x) = P{X =x} (d) Find the cumulative distribution function of X:...
