CHAPTER 06 - Continuous Random Variables
CHAPTER 6Continuous Random Variables
Intervals of values.
By finding areas under the curve.
f(x) 0 for all x; area under the curve equals 1.
Relative likelihood that x will be near the g
Chapter 07 - Sampling and Sampling Distributions
CHAPTER 7 Sampling and Sampling Distributions
A random sample is chosen by assigning each unit in the population a unique identifying
number and then utilizing a random digit table to identify the units
CHAPTER 08 - Confidence Intervals
CHAPTER 8Confidence Intervals
8.1 There is an entire population of possible sample means. A confidence interval is constructed to
be confident that the true value of is contained in that interval.
95% of the time
CHAPTER 09 - Hypothesis Testing
CHAPTER 9Hypothesis Testing
Type I error: reject H 0 when H 0 is true
= probability of a Type I error
Type II error: do not reject H 0 when H 0 is false
= probability of a Type II error
Because the probability
CHAPTER 10 - Statistical Inferences Based on Two Samples
CHAPTER 10Statistical Inferences Based on Two Samples
Sampled populations are normally distributed with equal variances.
Sampled populations are approximately normal.
