A telegraphic communications system transmits the signals dotand dash. Assume that the statistical properties of the obstaclesare such that an average of 2/5 of the dots and 1/3 of the dashesare changed. Suppose that the ratio between the transmitted dotsand the transmitted dashes is 5:3. What is the probability that areceived signal will be the same as the trans mitted signal if (a) thereceived signal is a dot, (b) the received signal is a dash.

Section 5.4 (please help with TI-84 calculator) :) The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n=61, find the probability of a sample mean being less than 20.1 if mean is 20 and standard deviation is 1.18. For a sample of n=61, the probability of a sample mean being less than 20.1 if mean is 20 and standard deviation is 1.18. Round to 4 decimal places
The average speeds of cars on a highway are distributed according to a normal distribution. Today, John is on his way to work. As he enters the highway, he notices a car speeding by at 150 km/hr. Ten seconds later, another car speeds by at 160 km/hr. John concludes that today, cars must be going faster for some reason. A few minutes later, John gets into a minor accident. Once again, he concludes that it was inevitable - he got into the accident because cars were driving faster today. Explain what fallacies - if any-are involved in both of John's claims. Is John justified in his conclusions?
The amount of liquid in a particular group of bottles is normally distributed. The mean is 1.95 L and the standard deviation is 0.15L. If a bottle is chosen at random, find the probability that the amount of water is between 1.88 L and 2.15 L Show all work as in the lessons. Paragraph B I U = I ***

The scores in a large Algebra class are normally distributed with a mean of 65 and a standard deviation of 11. If a random sample of 25 students is selected, find the probability that the sample mean will be between 63 and 70.
The bottom panel of figure 1 (p. 311) shows the probability histogram for the total number of spots when a pair of dice are rolled. (a) The chance that the total number of spots will be between 7 and 10 (inclusive) equals the area under the histogram between ___and ___ (b) The chance that the total number of spots will be 7 equals the area under the histogram between ___ and ____
Suppose that Mary, Gary, and Larry have been asked to randomly sample 100 patients' visit records from a file of 2000 patient records and record the amount of time the attending physician spent with each patient. Gary suggests the time of year during which the patient was seen may be a confounding variable and strongly advises dividing the year into quarters (Jan - Mar, Apr-Jun, Jul-Sep, Oct- Dec) and randomly selecting 25 patient records from each quarter. Which of the following best describes Gary's sampling plan? (A) A simple random sample (B) A systematic random sample (C) A stratified random sample (D) A cluster sample (E) A convenience sample
