The oldest and most commonly used cell line in Biology is the HeLa cell line, named after Henrietta Lacks, whose cervical cancer cells were taken without her consent in 1951 to create this cell line. The issue of data privacy and consent is very important to data science! You can read more about this topichere.

The HeLa cell line is missing from our dataset. If we know that the HeLa Copy Number value is 0.5, what is the predicted mRNA Expression (Affy) value? Use the values in parameters that we derived in Question 1.7, and assign the result to hela_affy.
