Test the following function to determine whether it is a probability function. If it is not, then make it into a probability function. (Give your answers correct to one decimal place.) R(x) = 0.2, for x = 0, 1, 2, 3, 4 (a) List the distribution of probabilities. R(0) = R(1) = ...
Sorry, but this is the way it is written, that is why I do not understand it.
I don't know, is the answer 5-10=5 for mean????
Consider the probability function. (Give your answers exactly.) P(x) = 5 − x 10 , for x = 1, 2, 3, 4 (a) Find the mean. (b) Find the standard deviation.
Find z, given the following. (Give your answer correct to two decimal places.) x = 56, ì = 45 and ó = 5.3 z =
Find the area under the standard normal curve between z = 0.7 and z = 2.15, P(0.7 < z < 2.15). (Give your answer correct to four decimal places.)
Sorry I hit the wrong one, not sure who this is but it helped me too...you also answered one of my questions and I was saying thank you for it.
Statistics answer check
I got 3.48 as the answer
