Question Transactions Let T1 transfer $50 from A to B, and T2 transfer 10% of the balance from A to B. And example of a serial schedule in which T1 is followed by T2 is shown below: T1 T2 read(A) A:=A-50 write(A) read(B) B:=B+50 write(B) commit read(A) temp:=A*0.1 write(A) read(B) B:=B+temp write(B) commit Show a CONCURRENT execution of T1 and T2 that produces a SERIALIZABLE schedule in a table just like the one above.

The worldwide market share for the Chrome web browser was 56.43% in a recent month. Suppose that you decide to select a sample of 100 students at your university and you find that 60 use the Chrome web browser. a. Use the five-step p-value approach to determine whether there is evidence that the market share for the Chrome web browser at your university is greater than the worldwide market share of 56.43%. (Use the 0.05 level of significance.) b. Suppose that the sample size is n = 600, and you find that 60% of the sample of students at your university (360 out of 600) use the Chrome web browser. Use the five-step p-value approach to try to determine whether there is evidence that the market share for the Chrome web browser at your university is greater than the worldwide market share of 56.43%. (Use the 0.05 level of significance.) c. Discuss the effect that sample size has on hypothesis testing. d. What do you think are your chances of rejecting any null hypothesis concerning a population proportion if a sample size of n = 20 is used?
