... (b) Following slide 17, ch3 use this formula for the standard error: SE=(p^ (1-p^ )/n)½ . SE = (.5375*.4625/400)½ = 0.02493 (c) What is the p-value for the test H0:p=.5, H1:p≠.5 , given this sample? Interpret this number. The p-value is defined in terms of the t-statistic t = (.5375-.5)/.02493 = 1.5 ...

... under the null hypothesis. For example, if we see that T (D) falls outside of the interval defined by the 1st and 99th quantile of p0 (T ), then it is reasonable to suspect that D was not, in fact drawn from p0 (D), but rather from some other distribution, and we would reject the null hypothesis her ...

Chi Square test
... – Test of deviation from expected frequencies: Test whether the observed frequencies deviate from expected frequencies (e.g. using a dice, there is an a priori chance of 16.67% for each number) – Test of association: Finding relationship between two or more independent variables (e.g. test relation ...

Calculating with Significant Digits
... Every measurement has some error associated with it. Even if you are extremely careful, the best you can do is estimate the last digit beyond where your measuring tool measures. This causes some trouble with calculations. If you are finding the area of a piece of land, for example, when you multiply ...

If our data were not normally distributed or if one or mare variables were ordinal, we should use the Spearman correlation. The only ch ...
