STAT PROB Flashcards
fundamental importance, justifies the use of normal curve methods
central limit theorem
range of values that approximate a parameter
estimate
process of determining parameter values
estimation
decision, evaluating claims about population. testing assumption in popu
hypothesis testing
assumption or conjecture which may be true or not
hypothesis
initial claim, no significant difference
null hypothesis
contrary of null hypothesis
shows significant difference
alternative hypothesis
equal to, same as, not changed from, is
null
not equal, different from
greater than, higher, longer
less than, below, lower
alternative hypothesis
not equal
greater than
less than
known as critical region, causes to reject the null hypothesis
rejection region
known as acceptance region, causes us to fail to reject the null hypothesis
non rejection hypothesis
point or boundary, determine if the null hypothesis would be rejected
critical value
evaluating the value of parameter
statistic hypothesis
seperates the rejection region from the acceptance region
critical value, z critical
degree of significance in which we reject or not
dictated by null hypothesis
level of significance
