Of these, 3/4 were interested in the same profession as one or both of their parents. If this latter group is made up of 15 students, how many first-year women are there?In a population of 10,000, there are 5000 nonsmokers, 2500 smokers of one pack or less per day, and 2500 smokers of more than one pack per day. During any month, htere is an 8% propability that a nonsmoker will begin smoking a pack or less per day, and a 4% probablility that a nonsmoker will begin smoking more than one pack per day. For smokers who smoke a pack or less per day, there is a 10% probability of quitting and a 10% probability of increasing to more than a pack per day.

- In an order placed at Gerdau, the customer requested some rolls of "25.4 kg Round Wire Rod", others of "26.99 kg Round Wire Rod" and also rolls of "25.4 kg Hexagonal Wire Rod" and "25.4 kg Hexagonal Wire Rod". 26.99 kg". It is known that 25% of rolls of "Round Wire Rod" are 26.99 kg and that, among rolls of 26.99 kg only, those of "Hexagonal Wire Rod" represent 25%. Also, 30% of the total number of rolls ordered is "Round Machine Wire of 25.4 kg". Choosing a roll at random, among all orders, the probability that it is a roll of "26.99 kg Hexagon Wire Machine" is approximately:Construct a Venn Diagram for the scenario. Suppose that a total of 208 students are enrolled in a Math course which offers three classes under Instructor X, Instructor Y, and Instructor Z. 4 students are enrolled under all three instructors. 48 students are enrolled under Instructor. Y. Twice as many students are enrolled under Instructor Y and Z (but not Instructor X) as those who are enrolled under both Instructor Y and X (but not Instructor Z), and 4 times as many as those enrolled under all three instructors. 124 students are enrolled in Instructor Z. 27 students are not enrolled in any class. Students enrolled under both Instructor Y and Z (but not Instructor X) is exactly the same size as the students enrolled under both Instructor X and Z.In an imaginary survey, we wanted to find out if there is a connection between morning sickness and sleeping position. A random sample of 400 people was selected for the survey. The respondent had to define himself as either a morning person or a non-morning person and tell the position in which he typically sleeps.186 respondents classified themselves as morning timers and 214 respondents as non-morning timers.Of the morning owls, 127 reported that they usually sleep on their side, 24 on their stomach and 35 on their back.Of the non-morning people, 156 reported that they usually sleep on their side, 29 on their stomach and 29 on their back.Use the chisq.test() function to test the null hypothesis that there is no connection between morning knitting and sleeping position. What is the p-value? Give the answer to four decimal places. Remember the correct decimal separator.
- A marketing research group conducting a telephone survey must contact at least 150 wives and 120 husbands. It costs P100 to make a daytime call and (because of higher labor costs) P150 to make an evening call. On average, daytime calls reach wives 30% of the time, husbands 10% of the time, and neither of these 60% of the time, whereas evening calls reach wives 30% of the time, husbands 30% of the time, and neither of these 40% of the time. Staffing considerations mean that daytime calls must be less than or equal to half of the total calls made. How many should be interviewed at each period to minimize the cost of completing the survey? fomulate the LP Model; identify the decision variables used in the model; and determine the optimal solution using graphical method.A survey of 500 farmers showed that 0f the farmers 129 grew only wheat, 108 grew only corn and 90 grew only oats. 210 grew wheat, 62 grew wheat and corn , 57 grew wheat and oats and 180 grew corn.
