2. Carbon dioxide is an odorless, colorless gas that constitutes about 0.035% b volume of the atmosphere. It affects the heat balance by acting as a one-way screen. It lets in the sun's heat to warm the oceans and the land but blocks some of the infrared heat that is radiated from the earth. This reflected heat is absorbed into the lower atmosphere, producing a greenhouse effect which causes the earth's surface to become warmer than it would be otherwise. Systematic measurement of CO2 began in 1957 with Charles D. Keeling monitoring at Mauna Loa in Hawaii. Assume that these CO2 readings (in ppm) are obtained: 319 338 337 339 328 325 340 331 341 336 330 330 321 327 337 320 343 350 322 334 326 349 341 338 332 339 335 338 333 334 a. Estimate u and o? using the method of moments estimators. b. Find an unbiased estimate for o?.

Please solve this question i will rate you Probability and statistics are related areas of mathematics which concern themselves with analyzing the relative frequency of events. Both subjects are important, relevant, and useful. But they are different, and understanding the distinction is crucial in properly interpreting the relevance of mathematical evidence. In this discussion please discussion how probability and statistics are related and the differences between the two fields of mathematics.
