If a random sample of 10 pots is inspected for flaws, calculate the probability that the random sample contains at least three pots with flaws, giving your answer to three significant figures. [0.474] Solution. Example 2.2. The probability that a person supports Party A is 0.6. Find the probability that in a randomly selected sample of 8 voters ...

What are the examples of probability sampling?
Example: If our sample is: 14, 7, 9, 2, 16, 18. then X(3) = Section 2.2: Estimation • Often we use a statistic to estimate some aspect of a population of interest. • A statistic used to estimate is called an estimator. Familiar Examples: • The sample mean: • The sample variance: • …

(note the sample space is not equally likely, we can use Example 2 to help fill in the probabilities) Example 4: Roll a fair die and count the number of pips on the upside. S={1,2,3,4,5,6} Example 5: Roll 2 fair dice and count the pips on each die. There are 36 equally likely outcomes.

The approximate probability, as illustrated in Figure 5.4, is. That is, about 98% of all samples have a sample proportion that is at least 0.58. Because the sample was large, this normal approximation is quite accurate. It misses the software value 0.9802 by only 0.0009. Figure 5.5 The normal probability calculation for Example 5.10

Sample Space (of an experiment): The collection of all the possible outcomes (or sample points). Example 1. Roll 1 die: Sample space = Example 2. Toss 2 coins: Sample space = The probability of a sample point is a number between 0 and 1 that measures the likelihood that this outcome will occur when the experiment is performed.

For example, what is the probability that T will be less than 2 and 3 minutes. A common way to describe probabilities in situations such as this is by means of an integral. We try to find a function f(t) such that the probability that T lies in any interval a ( t ( b is equal to , i.e. (1) Pr{ a ( T ( b } = .
