Calculate the P-value 6. State whether the Null Hypothesis is rejected (or not). 7. State you Conclusions. 8. State the assumptions that you were required to make to ensure that these conclusions were valid. A) How does increasing CO2 levels in the atmosphere affect the growth of Lodgepole pine seedlings? To investigate this, a scientist conducted an experiment where 80 seedlings were randomly assigned to individual growth chambers, and the seedlings were exposed to an atmosphere with a 3% increase in CO2 levels. After 6 months, the average change in the biomass of the seedlings was measured, and the sample mean was found to be 13.2 grams. It was also known that the population standard deviation for a 6-month-old pine seeding was 3.4 grams. Test to see if average change in seedling weight was greater than 15.2 grams at the 0.1% level of significance..
