    Question Data Analysis

    two thirds of the 36 bicycles in the store were blue, and the rest were red. Of the red bicycles,8 were ten speed bikes. Is it valid to say that there were more ten speed bikes in the store than any other kind? Explain

    There are 24 blue bikes, and 12 of other colours. of these other colour bikes
    8 are red an 10 speed.

    Now without further assumptions this thiss us nothing about the number of
    gears on the remaining 28 bikes.

    Now you could try assuming that the 12 non-blue bikes consist of only red
    bikes and that these constitute a random sample as far as numbers of gears
    are concerned. Then you could try constructing an hypotheseis test that
    of the 24 blue bikes 10 or more are 10 speed.
