Wire electrical-discharge machining (wedm) is a process used to manufacture conductive hard metal components. it uses a continuously moving wire that serves as an electrode. coating on the wire electrode allows for cooling of the wire electrode core and provides an improved cutting performance. an article gave the following sample observations on total coating layer thickness (in µm) of eight wire electrodes used for wedm. 21 16 29 36 42 25 24 25
calculate a 99% ci for the standard deviation of the coating layer thickness distribution. (round your answers to two decimal places.) , is this interval valid whatever the nature of the distribution? explain.
yes, there are enough data points for this interval to be valid.
no, validity of this interval requires that coating layer thickness be, at least approximately, normally distributed.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
