Please, tell whether the statement is TRUE or FALSE.
1) The F distribution is symmetric, and its mean is close to 1.
2) A small P-value indicates that the two variables in a two-way table are associated.
3) If the null hypothesis of an ANOVA F-test is true, the F statistic is greater than 1.
4) The more similar the conditional distributions in a two-way table are, the smaller the P-value of the chi-square test becomes.
5) In a two-way table, if the expected counts are about the same as the observed counts, we reject the null hypothesis.
6) The larger the chi-square statistic, the stronger the evidence against the null hypothesis.
7) In a two-way table, if the expected counts are about the same as the observed counts, we reject the null hypothesis.
