• Typically a parameter cannot be calculated from sample data. • A statistic is a function of random variables. • Given the data, we can calculate the value of a statistic. Examples of statistics: Order Statistics • The k-th order statistic for a sample X1, X2, …, Xn is denoted X(k) and is the k-th smallest value in the sample.

A would be impossible to calculate if the population weren’t normal. B and C would remain the same since 60 > 30, so the sampling distribution of sample means is normal, and the equations for the mean and standard deviation are valid. 2. Suppose that 47% of all adult women think they do not get enough time for themselves.

Suppose the average score for all people on an exam is 82 with a standard deviation of 10 and we take a random sample of size 40 and find the mean of that sample. (This is similar to assuming the mean weight of all winged beans was 525g with a standard deviation of 110g and finding samples of size 22)

The power is a probability and it is defined to be the probability of rejecting the null hypothesis when the alternative hypothesis is true. After plugging in the required information, a researcher can get a function that describes the relationship between statistical power and sample size and the researcher can decide which power level they ...

What is the probability that the sample mean differs from the population mean (on either side) by more than 4 hours? Suppose that a second (independent) random sample of ten students was taken. Without doing the calculations, state whether the probabilities in (a), (b), and (c) would be higher, lower, or the same for the second sample.
