Computer errors in numerical methods
... For the values of ε close to 0, the values of 3-2/ε and 1-2/ε are very close to -2/ε, so the value of xn is very close to 1, which is a true value. However, xn-1 = (1-xn)/ε will give nonsense, because 1-xn will be under influence of the error calculated in xn, and even greater error will be made by ...

... 4) Past results from the National Health Survey suggest that the head circumferences of 2month-old girls have a mean of 40.05 cm and a standard deviation of 1.64 cm. Assume the distribution is normally distributed. a) Use the range rule of thumb to find the minimum and maximum “usual” head circumfer ...

... • A type 2 error is made if the alternative hypothesis is true, but you fail to choose it. • A type 2 error can only be made if the alternative is true. • The probability of doing that depends on which part of the alternative hypothesis is true, so computing the probability of making a type 2 error ...

... The three types of probability are classical, empirical, and subjective. Classical probability uses sample spaces. Empirical probability uses frequency distributions and is based on observations. In subjective probability, the researcher makes an educated guess about the chance of an event occurring ...
