A national newspaper reported that the state with the longest mean life span is Hawaii, where the population mean life span is 76 years.

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 %3D sample standard deviation Sno fert. = 0.8 Sfert. 0.9 sample size Nno 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. What is the critical value for this test? O qt(0.95, df = 109) = 1.658953 O qt(0.9, df = 228) = 1.285276 O qt(0.9, df = 119) = 1.288706 O qt(0.9, df = 109) = 1.289367 %3D
