    Probability of biochemical experiment, distribution

    In a biochemical experiment, n organisms are placed in a nutrient medium, and the number of organisms X which survive for a given period is recorded. The probability distribution of X is assumed to be given by P(X=k)=\frac{2(k+1)}{(n+1)(n+2)}\ for\ 0 \leq k \leq n, and 0 otherwise 1)...

    Probability of genetic experiment on cell division

    A genetic experiment on cell division can give rise to at most 2n cells. The probability distribution of the number of cells X recorded is: P(X=k)=\frac{\theta^k(1-\theta)}{1-\theta^{2n+1}} for\ 0 \leq k \leq 2n where \theta is a constant with 0<\theta<1 What are the probabilities...

    Which statistics test should I use?

    For the final project in my statistics class, we need to conduct and evaluate our own survey or case study. The hypothesis I'm testing is whether or not a senior in high school who has made his or her college decision will get more sleep at night. I have my data collection, I just do not know...

    Not so simple coin experiment

    Can someone help me with some reference or any kind of a hint for the problem, which goes like this: You flip each of n coins repeatedly until it shows heads. Let X be the number of coins that require at least five flips. Find P(X = 0) and E[X]. I have tried to approach it by employing the...

    Exponential function with espected behavior - removal experiment in ecology

    I'm working with bird fatalities in windfarms and one of the required parameters to estimate mortality is the probability of an animal remain in the field at a given time, in order to be available for detection while a field work session. (which will be another probability to be accounted for)...

    referrence of physics laws in my experiment

    I've got a SAC which is my own experiment. The experiment is measure the Sag in a supported beam (A.K.A putting weights on top of a flexible ruler supported at both ends and measuring how much the ruler bent) Since i have to make referrence to law's and elaborate how these laws are imposed on...

    Binomial Experiment Question

    A binomial experiment consists of n=9 trials. Let B = total number of successes observed. Consider the situation where we wish to test H_0 : p \ge 0.4 vs H_1 : p < 0.4 If the test statistic is B and the rejection region is R = {b: b \le 1} Then calculate the significance level...

    space of an experiment

    The sample space of an experiment is {A,B,C,D} and P(A)-0.1, P(B)=0.3. P(C)=0.4, P({A,C})= what? My answer is 0.1x0.4=0.4 is this right, I'm not sure if I set the problem up right. thanks for any help given.
