A farmer wants to see if a new kind of fertilizer can help him grow better fruits. He prepares two separate plots of land and adds the fertilizer in one of those only. After a month he measure the weights of the fruits in each plot. Here are the results: plot 1 (no fertilizer) plot2 (fertilizer) sample mean Ino fert. = 3.5 Tfert. 3.8 sample standard deviation Sno fert. 0.8 Sfert. 0.9 sample size Ngo fert. = 120 nfert. = 110 Should this farmer invest in fertilizers? That is, is the mean weight of fruits significantly higher for the plot with fertilizer compared to the plot without it at the a = 0.1 level. Choose the appropriate set of hypotheses. O Ho : Hfert. – Huo fert. = 0 Ha : Hfert. - Hno fert. 7 0 Ho : ¤fcrt. – Tno fert. = 0 Ha : Ffort. – Fno fort. # 0 Ho : Hfert. - Hno fert. = 0 Ha : Hfert. - Hno fert. > 0 Ho : Tfert. – Tno fert. = 0 H. : Tfert. – Tno fert. > 0

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: BMI) if a researcher would like to determine if there is a significant difference in the "BMI" before ("Pre") and after ("Post") the treatment or therapy? Dataset for this can be retrieved on the given Excel.   1. What is the computed p-value for the given data on the "BMI" before ("Pre") and after ("Post") the treatment or therapy? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the "BMI" before ("Pre") and after ("Post") the treatment or therapy? 2. What is the computed Mean of "Pre" on the given data for BMI? Round it off to two decimal places. 3. What is the computed Standard Error of "Post" on the given data for BMI? Round it off to two decimal places.
