statistics, are my calculations correct?
posted by mary- please check calculations. .
classify the following as discrete or continuous random variables:
a) the time it takes to run a marathon- i think that it is discrete
b) the number of fractions between one and two- i think that it is discrete?
c) a pair of dice is rolled and the sum to appear on the dice is recorded- i think that it is discrete
d) the length of a broad jump- i think that it is continuous.
*am i correct and if not what would i need to change? please clarify with specifics. thank you.
statistics, are my calculations correct? -
a) If length is continuous, wouldn't time also be continuous?
b) The fractions can get smaller and smaller (e.g., 1 and 1*10^-9)
Otherwise, I think you are correct.
For your own safety, it is better not to use your whole name.
