Fisher's famous iris dataset (1936) includes 50 observations each of 3 types of iris plants: Setosa, Virginica, and Versicolor. Among other attributes, the sepal length (in cm) was recorded for each observation. The average sepal length for each type of iris plant is given below: Setosa: 5.006 cm Virginica: 6.588 cm Versicolor: 5.936 cm Note: For this data, SSW = 38.96. (a) Write down and explain the ANOVA model. (b) Perform an F test to assess whether the sepal lengths are the same for all three types of iris plants. Use x = 0.1.

50 people men and women were asked if they watched at least one sport on tv. 20 of the people surveyed are women, but only 9 of them watch at least one sport on tv. 16 of the men watch at least one sport on tv. make a a two-way table and a relative frequency table to represent the data.

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
