Chapter 2: Frequency Distributions
... One first step in summarizing data is to create a frequency distribution showing the number of observations for each observed data value. (In my experience, frequency distributions group the data, and counts are provided to show numbers or percentages of observations within various ranges). Sometime ...

Since the null hypothesis (μ = 3.25) is not rejected, there is insufficient evidence to conclude that the mean length of a phone call on a cell phone is greater than 3.25 mi ...

The null hypothesis attempts to show that no variation exists between variables, or that a single variable is no different than zero. It is presumed to be true until statisti ...

... Pr > |t| - The p-value is the two-tailed probability computed using t distribution. It is the probability of observing a greater absolute value of t under the null hypothesis. For a onetailed test, halve this probability. If p-value is less than the pre-specified alpha level (usually .05 or .01) we ...
