The sample mean is far (too many standard deviations) from 20. The sample mean is not equal to 20. The sample mean is close (too few standard deviations) to 20. The sample mean is equal to 20. Problem 4: In the P-value approach, relatively small values of the P-value correspond to situations where. The classical approach does not apply

Suppose we consider these 51 steers on the new diet as a random sample taken from a population of all possible steers that may be fed the diet now or in the future. Use the sample data given below and =.01 to test the research hypothesis that the mean live weight for …

a) if you increase your sample size, will always get closer to the population mean. b) the standard deviation of the sample mean is the same as the standard deviation from the original population c) the mean of the sampling distribution of is the population mean. d) always has a Normal distribution. 7.

Or, see if estimate of population (sample mean) is reliable (a good estimate). - Instead of creating a distribution of scores, create a distribution of MEANS. - Can INFER if sample is probable/improbable from the population or vice-versa.

A) is estimating the population mean using the sample mean B) is using the sample variance as an estimate of the population variance C) is using data, rather than theory. to judge that the carbon content is normal D) is using data from a specific day only E) has a small sample, and a z-confidence interval should never be used with a small sample

The interval [7.8, 9.4] is an attempt to capture the actual population mean, and is not representative of the alcohol contents of individual bottles. d) This statement is incorrect. Although we expect that 95% of the confidence intervals to contain the population mean, we cannot say that in 100 trials exactly 95 intervals will contain the mean.

Parameters versus Statistics: Parameter is some number that describes the Population. Statistic is some number that describes the Sample. Examples of parameters we’ve talked about: median of the population, mean of the population , variance of the population , standard deviation of the population, .

A common test statistic is a t-value. In this case, we are testing the value of one population mean, and the t-value (or sometimes used - a z value) is a measure of “how far” the sample mean is from the population mean that is specified in the null hypothesis.
