could you help giving me explanation on these problems ? Thank you .

Problem 1. An experiment was done to assess in vitro digestibility (IVD) of dried forage samples for alfalfa grown at different temperatures. The object is to determine if growing temperatures affected the feeding quality of alfalfa. There are four observations for each temperature, with data layout as follows: Temperature (C ) 17 22 27 32 X X x What kind of experimental design was conducted here? O A. Paired comparison design B. Randomized complete block design O C. Latin square design O D. Completely randomized design Question 2 Not yet Regarding Problem 1. Calculate the observed value of the F statistic in the following incomplete ANOVA table: answered Points out of Source df SS MS Fo 10.0 Temperature 5.86 P Flag question Error Total 7.67 O A 12.011 O B. 13.011 O C. 3.011 O D. 2011 Question 3 Not yet Regarding Problem 1. Can you conclude that the growing temperatures affect the feeding quality of alfalfa? answered Points out of 50 Flag question O A. Yes O B. NO Question 4 Problem 2. A plant scientist investigated plant uptake of heavy metals (for example, nickel) when four rates of sludge applications were used. For a single variety of sweet corn, a total of 20 plants were established. Not yet The plants were individually potted and 5 were randomly chosen to receive each rate of sludge. After a designated period of time following the sludge application, the leaves were taken from each plant and Points out of 5.0 analyzed for presence of the heavy metal. The proportion of leaves with the heavy metal was used as the response. F Fing question What is the experimental unit? O A. A set of five plants O B. A plant O C. The leaves Question 5 Not yet Regarding Problem 2. What type of experiment was conducted here? nswered Points out of 10.0 O A Completely randomized design Flag question O B. Simple comparative design C. Paired comparison design D. Latin square design
