Chapter 5: Q T5.6. (page 336)

What is the probability that a student has a GPA under 2.0 or has skipped many classes? (a)0.080(b)0.281(c)0.285(d)0.365(e)0.727

Short Answer

Expert verified

The correct answer is(c)0.285

Step by step solution

01

Step 1. Given

The table is:
02

Step 2. Concept

The probability of an event=numberoffavourableoutcomestotalnumberofoutcomes

03

Step 3. Calculation

The likelihood that she has a GPA of less than 2.0or has skipped several classes is calculated as follows:

P(<2.0orMany)=80+175+25+51000=285/1000=0.285

As a result, 0.285 is the required probability.

As a result, the best solution is (c).

Color-blind men Refer to Exercise 25. Suppose we randomly select 4 U.S. adult males. What’s the probability that at least one of them is red-green

color-blind? Design and carry out a simulation to answer this question. Follow the four-step process.

In government data, a household consists of all occupants of a dwelling unit. Choose an American household at random and count the number of

people it contains. Here is the assignment of probabilities for your outcome:

The probability of finding 3people in a household is the same as the probability of finding 4people. These probabilities are marked ??? in the table of the distribution. The probability that a household contains 3 people must be

(a) 0.68(b) 0.32(c) 0.16(d) 0.08(e) between 0 and1, and we can say no more.

Random assignment Researchers recruited 20volunteers—8men and 12women—to take part in an experiment. They randomly assigned the subjects

into two groups of 10people each. To their surprise, 6of the 8men were randomly assigned to the same treatment. Should they be surprised? Design and carry out a simulation to estimate the probability that the random assignment puts 6or more men in the same group. Follow the four-step

process.

During World War II, the British found that the probability that a bomber is lost through enemy action on a mission over occupied Europe was 0.05 Assuming that missions are independent, find the probability that a bomber returned safely from 20 missions.

Who eats breakfast? Students in an urban school were curious about how many children regularly eat breakfast. They conducted a survey, asking, “Do you eat breakfast on a regular basis?” All 595 students in the school responded to the survey. The resulting data are shown in the two-way table

below.7 Male Female Total Eats breakfast regularly 190110300 Doesn’t eat breakfast regularly 130165295Total320275595

(a) Who are the individuals? What variables are being measured?

(b) If we select a student from the school at random, what is the probability that we choose

  • a female?
  • someone who eats breakfast regularly?
  • a female who eats breakfast regularly?
  • a female or someone who eats breakfast

regularly?
