Problem 2.When someone presses SEND on a cellular phone, the phone attempts to set up a call bytransmitting a SETUP message to a nearby base station. The phone waits for a response, and ifnone arrives within 0.3 seconds, it tries again. If it doesn't get a response after n= 4 tries, thephone stops transmitting messages and generates a busy signal.(a) Draw a tree diagram that describes the call setup procedure.(b) If all transmissions are independent and the probability that a SETUP message will getthrough is p, what is the PMF of K, the number of messages transmitted in a call attempt?(c) As a manager of a cellular phone system, you want the probability of a busy signal to beless than 0.01. If p = 0.8, what is the minimum value of n necessary to achieve that goal?(d) Find and sketch the CDF of N, the number of attempts made by the cellular phone for p=1/3

Find the median, first quartile (Q1) and the third quartile (Q3) for the data shown, which is already sorted. The number of data is n= 11. Katye Kozak's algorithm: Sort the data and compute the median. When n is an odd number, the median is the center value. When n is an even number, the median is the center value. After computing the median, Q1 is the median of the 1st half of the data, not including the median value. Q3 is the median of the 2nd half of the data, not including the median value.

In a classic study of problem solving, Duncker (1945) asked participants to mount a candle on a wall in an upright position so that it would burn normally. One group was given a candle, a book of matches, and a box of tacks. A second group was given the same items, except that the tacks and the box were presented separately as two distinct items. The solution to this problem involves using the tacks to mount the box on the wall, creating a shelf for the candle. Duncker reasoned that the first group of participants would have trouble seeing a new function for the box (a shelf) because it was already serving a function (holding tacks). For each participant, the amount of time to solve the problem was recorded. Data similar to Duncker’s are as follows. Time to Solve Problem (in sec.) Box of Tacks Tacks and Box Separate 128 42 160…

A large bakery has many different products for sale. Suppose that 200 come in between 6am and 10am. Of the 200 customers 140 order donuts, 100 order cinnamon rolls, and 80 order both. Make a Venn Diagram to model the situation.
After a 30-member battalion fled, the general ordered the battalion to suffer decimation as punishment. In a decimation, one of out of every ten soldiers is killed. Assuming they are killed at the same time (so that it doesn't matter what order they are chosen), how many ways can the battalion be decimated?

A researcher wants to determine whether adolescents spend more time in a day around friends than adults do. He gathers a sample of n =10 adolescents (aged 12-17) and a sample of n =6 adults (aged 25-32). The researcher finds that the average time spent around friends for adolescents is M1= 3 hours with a SS1 of 44. He also finds that the average time spent around friends for adults is M2= 2 hours with a SS2 of 40. a. Do you use a one- or two-tailed test?

Why do zebras have stripes? One hypothesis is that stripes help keep biting flies away. Trinity wants to test this hypothesis with an experiment. She will use 15 horses as the subjects in her experiment, and assign them to 3 treatments, as follows: 5 horses will wear a fabric coat that is printed with zebra stripes, as shown above 5 horses will wear nothing 5 horses will wear a fabric coat that is printed with a solid grey colour Trinity will record a video of each horse for 1 hour. She will use the video to determine the number of biting flies that land on the horse's back. a) What types of experimental group do each of (i), (ii), and (iii) represent? Choose from: Main experimental treatment group Classical control Positive control Negative control b) Why is it important for Trinity to include group (iii) in her study? Provide a brief explanation. Hint: you can describe potential scenarios for results to help explain why group (iii) is needed. c) Can you suggest ONE potential…
You'd like to study social networks. Consider the following 26 people {A,B,C,...,X,Y,Z} in a social network graph. (These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 26? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here.
Rework problem 13 from section 1.4 of your text, involving sales calls. Assume the sales representative calls 7 customers, and each call has 3 possible results: reaches the customer in person, there is no answer, and gets an answering machine. A phone record is a list of the results of each call. How many different phone records are possible?
In a port rotation of a route, there are 4 ports. A vessel comes into the port#1 every Monday and leaves on Wednesday. The sailing time from one port to the next for all the ports is 10 days. Each port takes 2 days for the vessel to enter and leave. What is the lowest number of vessels required in the route to ensure the route has a vessel calling at the port #1 on every Monday?
