To make tests of hypotheses about more than two population means, we use the:
- ?normal distribution
- chi-square distribution
- analysis of variance distribution
- ?t distribution
?A continuous random variablex has a right-skewed distribution with a mean of 80 and a standard deviation of 12. The sampling distribution of the sample mean for a sample of 50 elements taken from this population is:
- ?not normal
- ?skewed to the left
- ?skewed to the right
- ?approximately normal
The modely = A + Bx is a:
- ?probabilistic model
- ?stochastic model
- ?nonlinear model
- ?deterministic model
?For a goodness-of-fit test, the frequencies obtained from the performance of an experiment are the:
- ?expected frequencies
- ?observed frequencies
- ?objective frequencies
- ?subjective frequencies
An error that occurs because of chance is called: ?
- ?probability error
- ?mean error
- ?nonsampling error
- ?sampling error
