... (a) Reject Ho if u < -1.645 so reject Ho at 5% (b) Reject Ho if u < -2.33 so reject Ho at 1%. Note: decision (b) is not the same as in the previous problem using a two-tailed test. Decisions based on one-tailed tests do not always agree with decisions based on two-tailed tests. This is to be expecte ...

... Solution. We show that d = 5 is the only number in the given set with this property. First note that if d 6= 5 and d 6= 10, then d is not the hypothenuse of a right triangle with integer sides, so the only moves of length d between lattice points are moves in horizontal or vertical direction. These ...

Probability of One Event
... In this section we calculate the probabilities of single events. We consider cases where all the possible outcomes are equally likely. For example, when you roll a fair dice you are equally likely to get any of the six numbers. (The words 'fair' or 'unbiased' mean that all outcomes are equally likel ...

Polygonal Numbers
... Thus, for each iteration, we add (m-1)+(n-2)(m-2) dots. Since m and m-2 are both constant, the only term that changes is (n-2). This leads to the common difference observation: each iteration, we add m-2 more dots than we added the previous iteration because the coefficient of the (m-2) term has inc ...

Law of large numbers
In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.The LLN is important because it ""guarantees"" stable long-term results for the averages of some random events. For example, while a casino may lose money in a single spin of the roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. It is important to remember that the LLN only applies (as the name indicates) when a large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be ""balanced"" by the others (see the gambler's fallacy)
