Chapter 7 Sampling Distributions of Estimates
... The value of the sample mean from a random sample will vary from sample to sample. So the sample mean (a statistic) is a random variable and it will have a probability distribution. This probability distribution is called the sampling distribution of the statistic. In Section 7.2 we learn about the ...

... 10) Researchers were interested in studying whether fruit flies actually sleep. A small part of the study used an infra-red motion sensor to see if flies moved in response to vibrations. Here are the results for low levels of vibration: 10 of the 64 flies responded to vibration while walking while 4 ...
