A Bacterial Buffet A biologist keeps dangerous bacteria of six
different kinds in a long glass tube
separated into six chambers by membranes.
She has noticed that, if she removes a
membrane, bacteria start fighting their
neighbours.
Those which are in a minority always die,
together with an equal number of the
enemy. Equal colonies eat each other
completely!
Originally, there were a million bacteria of
the first kind, two million of the second, and
so on, up to six million of the sixth kind.
Is it possible for her to open the membranes
in turn in some order so that no bacteria
survived? Explain your answer.

Say that a supplier claims they are 99% confident that their products will be in the interval of 50.02 to 50.38. you take samples and find that the 99% confidence interval of what they are sending is 50.00 to 50.36. what conclusion can be made? homework : 5vd. comparing sample confidence intervals with given intervals (links to an external site.)links to an external site. (3: 43) 5dc. confidence intervals in manufacturing, high vs low level of confidence, wide vs narrow (links to an external site.)links to an external site. (docx) the supplier is less accurate than they claimed the supplier products have a lower mean than claimed the supplier is more accurate than they claimed the supplier products have a higher mean than claimed
