So far this year, U.S.-listed biotech companies have raised roughly $9.4 billion in initial public offerings, already beating the $6.5 billion raised in all of 2018, the biggest year on record, according to Dealogic data going back to 1995. This year’s biotech issues have jumped an average of 34% on their first day of trading, the biggest average first-day pop for the sector since the tech boom in 2000. The recent surge in biotech stocks extends beyond IPOs, as investors chase companies working on potential vaccines to combat Covid-19.

The asking prices in thousands of dollars for 25 single family residences listed in a city in California are given below. 370.0 269.0 290.9 398.0 326.0 218.9 249.9 239.0 498.9 334.0 288.9 324.0 328.0 300.0 361.0 294.0 319.0 330.0 366.0 339.0 310.9 294.0 270.9 349.0 326.0 (a) Locate the largest and smallest prices and use the range to approximate the standard deviation (in thousands of dollars). $ thousand (b) Calculate the sample mean x (in thousands of dollars). x = $ thousand Calculate the sample standard deviation s (in thousands of dollars). s = $ thousand Compare s with the approximation obtained in part (a). The actual value is very close to the estimate, since the difference is within 5. The actual value is close to the estimate, since the difference is between 5 and 10. The actual value is not markedly different from the estimate, since the difference is between 10 and 20. The actual value is not close to the estimate, since the difference is more than 20. (c) Find the percentage of prices that falls into the interval x ± 2s. % Compare with the corresponding percentage given by the Empirical Rule. The proportion of measurements in this interval is not close to the proportion given by the Empirical Rule, since the difference is more than 2%. The proportion of measurements in this interval is close to the proportion given by the Empirical Rule, since the difference is within 2%..

1. Locking methods are one of the most common techniques used in concurrency control. There are different levels of lock use.

Make sure you clearly write down (a), (b) followed by your answers.

[6 marks] (a) Use the following scenario to illustrate and explain how a table-level lock and a page-level lock work.

Scenario:

Transaction 1 (T1) wants to update row 5 in Table A

Transaction 2 (T2) wants to update row 2 in Table A

Note: Page 1 contains rows 1-3 in Table A and Page 2 contains rows 4-6 in Table A

[4 marks] (b) Compare the advantages and disadvantages of a table-level lock and a page-level lock.
