#143. Global Temperatures A research group measured the Earth's globally averaged temperature T during June in 4 different years, and obtained the data listed in the table. Year T (K) 1994 286.73 1 2002 286.83 2 2008 286.90 3 2015 286.98 4 rows x 2 columns What is the expected global temperature in June 2016? I number (rtol=0.01, atol=0.0001) Give a prediction interval for the temperature in June 2017 at the 86% level. Ib number (rtol=0.01, atol=0.0001) ub number (rtol=0.01, atol=0.0001) In what year are you at least 90% confident that the expected June temperature first exceeded 286.78 K? Year number (rtol=0.01, atol=0.0001) A climate-skeptic questions whether the Earth is really getting warmer. How could you test this hypothesis. Compute the relevant test statistic and its associated P-value. (Note: report the absolute value for the statistic) t-statistic number (rtol=0.01, atol=0.0001) P-value number (rtol=0.01, atol=0.0001) What is your conclusion at a 5% significance level? O (a)…
