Fertilizer: A new type of fertilizer is being tested on a plot of land in an orange grove, to see whether it increases the amount of fruit produced. The mean number of pounds of fruit on this plot of land with the old fertilizer was 392 pounds. Agriculture scientists believe that the new fertilizer may change the yield. State the appropriate null and alternate hypotheses. The null hypothesis is Hu (Choose one) The alternate hypothesis is H. Choose one)
Q5 a) Demographic data from 126 countries is obtained for the year 2017. It is hypothesized that life expectancy (Y) is dependent on number of under five deaths (X2) , polio immunization coverage (D), Per capita Govt. Exp. on Health Care (X3) (in Rs crores), Per Capita GNI (in Rs crores) (X4) and Average number of years of Schooling (Xs). Polio immunization coverage =1 if yes and 0 otherwise. Following regressions were estimated: MODEL 1: = 0.903 – 0.561X2¡ + 2.008 X3i + 0.553X4¿ + 0.778 X5i + 3.638 D (0.405) se = (1.280) (0.765) (0.712) (0.491) R? = 0.787 RSS = 1339.8 MODEL 2: P, = 1.379 + 0.594 X31 + 2.139 D se = (0.406) (0.465) R? = 0.677 RSS = 1567.28 i.

Clinical research attempts to identify the risks of exposure tothe population in the workplace. In a group of 46 menBetween the ages of 25 and 36, changes in the function of their lungs have been measured. One of the variables of interest was the volumeexhalation force (VFE), which is the volume of air exhaled per second. At the end of a certain period, it was found that the VFE of `this sample decreased with an average of 0.27 liters and a deviation0.52 liter sample type. We know that the VFE increases by 0.1liter in healthy men of the same ageduring the same period of time. Can we conclude that the middle ofwork of this group plays a significant role in the growth ofVFE greater than 0.1 liter? Choose the appropriate hypothesis testto do. Give the value - P and your conclusion. Take α = 0.02.
Climate change 2013 Data collected from around the globe show that the earth is getting warmer. The most common theory relates climate change to an increase in atmospheric levels of carbon dioxide (CO2), a greenhouse gas. The mean annual CO2 concentration in the atmosphere (parts per million) is measured at the top of Mauna Loa in Hawaii (away from any local contaminants) and available at ftp://aftp.cmdl.noaa.gov/products/trends/co2/co2_annmean_mlo.txt The mean surface air temperature is recorded as the change in °C relative to a base period of 1951 to 1980.
