Glоbаl wаrming is а majоr issue facing the wоrld today. Documenting the mean surface temperature of the earth over time is one measure of global warming. The data below represents the mean surface temperature of the earth calculated every 10 years from 1930 - 2020. The data below gives the number of years past 1900 (considered year 0) and the mean surface temperature of the earth in degrees Fahrenheit. Year Years past 1900(x) Mean Surface Temperature oF (y) 1930 30 57.1 1940 40 57.3 1950 50 56.9 1960 60 57.2 1970 70 57.3 1980 80 57.6 1990 90 57.8 2000 100 57.8 2010 110 58.3 2020 120 58.7 1. Find the linear correlation coefficient r for this data set. Round to three decimal places. [r] 2. A hypothesis test is to be done to determine if there is linear correlation between years past 1900 and mean surface temperature. The null and alternative hypotheses are given below. Use a 0.05 level of significance.
