We asked UST employees to tell us how many megabytes of memory (RAM) theyhave on their computer. VWe would like to test to see if the mean amount of memoryis the same for three different academic departments. We have the memoryamounts for six faculty members' machines in the three departments shown below.Dept. 1Dept. 2 Dept. 3140964096 4096409620484096409620488192computer 481924096 81924096204840966.204881922048Here is the ANOVA table:Analysis of VarianceDFAdj SSAdj MSF-ValueP-ValueSource27962030.604Factor5592405XXX803908275359388ErrorXXTotal85983232XXState your decision for the ANOVA test and the reason for your decision.2.3.

Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2), which contributes to global warming. The CO2 emissions (metric tons per capita) for countries varies from 0.02 in Burundi to 44.02 in Qatar. Although the data set includes 214 countries, the CO2 emissions of 15 countries are not available on the World Bank database. The data set is too large to display but the data for the first five countries is given. Use the full data set with data on the 214 countries to answer the questions.

AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
