monica measures the number of bacteria that are living on her petri dish. each day, she measures the amount of change in the number of bacteria. these amounts create a geometric sequence. use the data in the table to determine the sum of the amounts of change in the bacteria after the seventh day.

x (day) y (amount of change in bacteria)

1 2

2 -8

3 32

4 -128

a] -6553.2

b] -10.8

c] 6554

d] 11.6

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
