Question

All hypothesized proportions must be the same in a goodness of fit test. True False If the sample size in a one-sample proportion test is less than 20, it becomes impossible to perform the test because the conditions cannot be satisfied. True False Large values of a chi-squared test statistic in a goodness of fit test are evidence against the null hypothesis because it indicates that the observed and expected counts are far apart True - False The standard error of the test statistic in a one-sample proportion test depends upon the sample proportion. True False

Explanation / Answer

1) false as proportions can be different between categories

2)true ; as for np and n(1-p) both to be greater then 20 minimum sample size is 20 for p=0.5.

3)true ; as large value of test statistic fill fall in critical region

4)false ;as it depends on population proportion
