Lyrical is a kind of contemporary dance that is used to describe dance that has more of a connected and continuous movement pattern (ie soft, gentle): and some other term probably exists to take over the dramatic, contrasting, sharp movement style that can also exist under the umbrella of contemporary.
Hard hat sizes can seem a bit mysterious. To measure for your hat size, place a soft cloth tape measure around the widest part of your head (this is usually just above the eyebrows). Pull the tape measure snug, but not tight. Convert inches to hat size using the sizing chart below.
Let (p hat) be the proportion of the SAMPLE having that characteristic. Then: 1) the MEAN of the sampling distribution is EXACTLY (p) 2) the standard deviation of the sampling distribution is square root of [(p(1-p)/n} These facts must be memorized. You will be called on to use the recipe in #2 to determine missing standard deviations. Because the mean of the sampling distribution of (p hat) is always equal to the parameter p, the sample proportion (p hat) is an UNBIASED ESTIMATOR of (p). The standard deviation of (p) hat gets smaller as the sample size n increases because n appears in the denominator of the formula for the standard deviation. That is, (p hat) is less variable in larger samples. The sample size n is under the square root sign, so to cut the standard deviation in half, we must take a sample four times as ...
