### Let A represent having soup and let B represent having salad for lunch. Which statement is true? Having soup and salad for lunch are independent events because $P\left(A\mid B\right)=P\left(A\right)\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}P\left(B\mid A\right)=P\left(B\right)$. Having soup and salad for lunch are not independent because $P\left(A\mid B\right)=P\left(A\right)\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}P\left(B\mid A\right)=P\left(B\right)$. Having soup and salad are not independent events because $P\left(A\mid B\right)\ne P\left(A\right)\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}P\left(B\mid A\right)\ne P\left(B\right)$. Having soup and salad for lunch are independent events because $P\left(A\mid B\right)\ne P\left(A\right)\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}P\left(B\mid A\right)\ne P\left(B\right)$ snowlovelydayM 2021-05-07 Answered

Use the appropriate nonparametric test to determine whether the data provide sufficient evidence to indicate a difference in the yields for the five different varieties of wheat. Test using $\alpha \alpha =.05$. b. How do the analysis of variance F test compare with the test in part a? Explain.

The majority of college-level probability practice problems will include questions related to statistics with the answers and explanations that will explain how a certain riddle has been addressed. Just think about flipping a coin or throwing dice as an example or finding a red marble in the bag with the green marbles. It is all about probability where the college probability will have more complex questions with the necessity of different equations and quantitative data questions where formulas must be used to determine the possibility of a certain outcome or prognosis. We offer help by letting you see various probability examples.
