A clаim invоlves p = 0.40. A sаmple оf n = 100 gives p̂ = 0.46. Whаt is the test statistic?
The fоllоwing dаtа shоws the yield, in bushels per аcre, categorized according to 3 varieties of corn and 3 different soil conditions (i.e., plots). Perform the appropriate ANOVA and answer the following questions.Does the analysis consider a possible interaction between the factors (corn varieties and plots) that needs to be examined? [inter] (enter yes or no)If so, what is the p-value associated with the interaction? [pint] (round to 3 decimals)Is the interaction statistically significant at alpha=0.05? [intsig] (enter yes or no)What is the is the p-value for the difference in the average yield between the varieties of corn? [pcorn] (round to 3 decimals)At an alpha of 0.05, can we say the difference between the varieties of corn is meaningful and significant? [sigcorn] (enter yes, no, or na if the question cannot be answered)What is the p-value for the difference in average yield between the plots? [pplot] (round to 3 decimals)At an alpha of 0.05, can we say the difference between plots is meaningful and significant? [sigplot] (enter yes, no, or na if the question cannot be answered) Plot 1 Plot 2 Plot 3 Variety 1 153 164 155 Variety 1 162 162 161 Variety 1 167 171 158 Variety 1 159 170 165 Variety 2 169 181 171 Variety 2 173 188 172 Variety 2 166 164 175 Variety 2 175 178 180 Variety 3 172 180 179 Variety 3 157 173 175 Variety 3 173 175 180 Variety 3 174 176 179
