A researcher is interested in the concentration of carbon dioxide in the atmosphere directly above Mauna Loa, a volcano in Hawaii. The researcher measures and records the concentration of carbon dioxide in parts per million (ppm) on 17 different days. These recordings (in ppm) are shown in the vector below. CarbonDioxide=c(342.33,353.64,337.84,341.18,316.05,365.45,332.24,361.94,325.72,347.76,336.56,327.91,339.39,316.71,324.63,351.52,336.68); a. Compute the following quantities for this data. round to at least five decimals if necessary Mean: __________ Median: ________ Standard deviation: __________ Q1: __________ Q3: __________

a. Compute the following quantities for this data. round to at least five decimals if necessary
Mean: __________
Standard deviation: __________
Q1: __________
Q3: __________
b. Suppose a new reading of carbon dioxide of 426 ppm is recorded. Would this value considered an outlier based on the sample above? Use any relevant values from part a. in your calculation if necessary.
- Yes
- No
- There is not enough information to determine if this value would be considered an outlier
c. In this dataset, the largest 50% of observations fall above what value? Use any relevant values from part a. in your calculation if necessary.
_____________ Round to at least five decimals if necessary
d. Unbeknownst to the researcher, the instrument being used to measure the carbon dioxide levels malfunctioned during the sampling process, leading to some of the levels being recorded as significantly higher than they actually were. Which of the following is the most likely type of bias introduced by this malfunction?
- Non-response bias
- Sampling bias
- Response bias
- This malfunction would not introduce any sort of bias
