Survey of vacationers. A survey is taken of 100 people who vacationed at a dude ranch. The following information was obtained:
17 took horseback –riding lessons, attended the Saturday night barbecue, and purchased a tour guide.
28 attended the Saturday night barbecue and purchased a tour guide.
24 took horseback-riding lessons and purchased a tour guide.
42 took horseback-riding lessons but didn’t attend the barbecue.
86 took horseback-riding lessons or purchased a tour guide.
14 purchased only a tour guide.
14 did none of these three things.
How many attended the barbecue? How many purchased a tour guide?

- b. According to the analyst, what is the probability that the confidence score is not 1? 11. Professor Sanchez has been teaching Principles of Economics for over 25 years. He uses the following scale for grading. Grade Numerical Score Probability A 4 0.10 B 3 0.30 C 2 0.40 D 1 0.10 F O 0.10 a. Depict the probability distribution graphically. Comment on whether or not the probability distribution is symmetric. b. Convert the probability distribution to a cumulative probability distribution. C. What is the probability of earning at least a B in Professor Sanchez's course? d. What is the probability of passing Professor Sanchez's course? 2. Professor Khurana expects to be able to use her grant money to fund up to two students for research assistance. While she realizes that there is a 5% chance that she may not be able to fund any student, there is an 80% chance that she will be able to fund two students. a.

Thank you.arrow_forwardA ladder 27 feet long leans against a wall and the foot of the ladder is sliding away at a constant rate of 3 feet/sec. Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of л/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the height of the firefighter above the ground, at the instant the angle of the ladder with the ground is л/3, find dh/dt= feet/sec. (b) If w is the horizontal distance from the firefighter to the wall, at the instant the angle of the ladder with the ground is л/3, find dw/dt= feet/sec.arrow_forward
- Two cars start moving from the same point. One travels south at 60 mi/h and the other travels west at 25 mi/h. At what rate (in mi/h) is the distance between the cars increasing four hours later? Step 1 Using the diagram of a right triangle given below, the relation between x, y, and z is z² = x²+ +12 x Step 2 We must find dz/dt. Differentiating both sides and simplifying gives us the following. 2z dz dt dx 2x. +2y dt dx dy dz x +y dt dt dt 2z dy dt × dx (x+y dt dy dtarrow_forwardAn elastic rope is attached to the ground at the positions shown in the picture. The rope is being pulled up along the dotted line. Assume the units are meters. 9 ground level Assume that x is increasing at a rate of 3 meters/sec. (a) Write as a function of x: 0= (b) When x=10, the angle is changing at a rate of rad/sec. (c) Let L be the the left hand piece of rope and R the right hand piece of rope. When x=10, is the rate of change of L larger than the rate of change of R? ○ Yes ○ Noarrow_forwardAt a local college, for sections of economics are taught during the day and two sections are taught at night. 70 percent of the day sections are taught by full time faculty. 20 percent of the evening sections are taught by full time faculty.
