In a survey, 205 people indicated they prefer cats, 160 indicated they prefer dots, and 40 indicated they don’t enjoy either pet. Find the probability that if a person is chosen at random, they prefer cats.
Explain in details.
Homework Answers
In the survey,
People prefer cats = 205
People prefer dogs = 160
People prefer neither pets = 40
Number of sample in the survey = (205+160+40) = 405
The probability that if a person is chosen at random, they prefer cats
= (Number of people prefer cats)/(Total number of sample)
= 205/405 = 41/81

CASE STUDY Cats or dogs—which is the better pet for relieving stress? To answer this age-old question, your DSC decided to test whether they should start a “Furry Friends” program for emotional support during exams using dogs or cats. To test the difference, they selected 40 random people who didn’t have a pet at home. Each person was randomly assigned to either a cat treatment or a dog treatment and asked to drop by the test room for 30 min...

In a recent poll, 4545% of survey respondents said that, if they only had one child, they would prefer the child to be a boy. Suppose you conducted a survey of 160 randomly selected students on your campus and find that 79 of them would prefer a boy.(a) Use the normal approximation to the binomial to approximate the probability that, in a random sample of 160 students, at least 79 would prefer a boy, assuming the true percentage 45%. (b)...

A large survey of people throughout the world has indicated that people claim that their favorite color is red. In fact, about 20% of the population claim that red is their favorite color. Suppose a random sample of n = 35 college students was surveyed and r = 8 of them said that red is their favorite color. Does this indicate that the color preference of all college students is different (either way) from that of the general population? Use...

Q7. A survey is being conducted in a city with 1 million residents. It would be far too expensive to survey all of the residents, so a random sample of size 1000 is chosen. The survey is conducted by choosing people one at a time, with replacement and with equal probabilities. Find exact probability that at least one person will get chosen more than once. Then use an approximation to calculate this probability.

A recent survey of 1500 residents in a city indicated that around 40% of the residents owned a home. Suppose that it is indeed true that 40% of the residents own a home. The sampling distribution for the proportion of home ownership is approximately normal with mean 0.40 and standard deviation 0.025. What is the probability the sample proportion of people who own a home will be less than 0.37?
