Many american cars feature speedometers that show kilometers per hour if you are required to drive 500 miles, and you know that one kilometer is approximately 5/8 of a mile, how many kilometers will you cover in that journey?

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?

F(x)= 4x g(x) =x-1 what is f(x) divided by g(x)

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 360, a standard deviation of 4, and a margin of error of 2.5%
