Suppose the probability that a household owns a pet is 0.45. (We can assume one house owning a pet is independent of the others.) Suppose we looked at two houses on a street, the Smiths and the Millers. What is the probability that the Smiths and the Millers both have a pet?

suppose that the probability we can find the virus in a single test is no better than flipping a coin, which is 50%. Suppose we conduct a series of independent test using the same patient's sample, and make the decision that the patient is contracted with the virus. If any one of these test is positive. How many independent tests do we need to carry out such that such a scheme give us a false positive rate (probability that a...

The t statistic compares two groups on one independent variable that has two levels. We can use the t statistic to compare a sample that has a level of an independent variable, or we can use two samples from the same populations and give them two different levels of an independent variable. You will design a two group study with one independent variable for this question. Choose an independent variable that has two levels. The two levels can be 1.)...

Suppose we have three cards. One is colored red on both sides, one is black on both sides, and one is red on one side and black on the other. We place these three cards in a hat and shuffle them. We draw one card and place in on the table, so only one side is visible. If that side is red, what is the probability that it’s the red-black card?

Suppose Sony sells a warranty on one of its products. They find the probability that a warranty holder files an accidental damage claim is 15%. The probability they file a claim on the battery is 35%. Each warrentt holder can only file up to one of each type of claim and file types independently of each other. Develop a table to help solve the problem. a) What is the probability that a warranty holder makes a claim on their warranty?...

Suppose we go back to the example from question 3. Suppose the probability remains at 16% but we now take a sample of size 100. What is the standard error of the proportion? What is the probability that the sample proportion of people who have white as ethnicity is between 10% and 25%? Two estimates are available for the same population parameter. Estimate one has a standard deviation of 9.3 and estimate two has a standard deviation of 9.4. Estimate...

Problem: Suppose that a couple will have 3 children. Assume that the probability of having a girl is .487 and the probability of having a boy is .513. Also assume that x is a random variable for the number of girls and find the probability where x is 0, 1, 2, or 3. In order words, answer the following probability questions. What is the probability that none of the three children will be girls? What is the probability that exactly...
