Use te below information to answer question 2 to 6.Apu performed study to determine a probability distibution for the number of tofu dogs purchased per day.The results are summarized in the folloiwng table.For these problems,either show the formula you use or write the command and output from excel. Find:
2) The mean (expected value) of the random variable is
3) The variance of the random variable is
4) The standard deviation of the random variable is
5) The probability that Apu sells exactly 8 tofu dogs in a day is
6) The probability that Apu sells 7 or more tofu dogs in a day is
7) Let X denote the payoff. Then X can take the following values
8) A simple random sample of 40 students are asked whether they have internet access at home. The number of students who do have home access is recorded
9) If X follows a binomial distribution with parameters n and p, the probability distribution of X is given by,
10) ) If X follows a binomial distribution with parameters n and p, the probability distribution of X is given by,
11) The mean of the random variable is
12) The standard deviation of the random variable is
13) The probability that x<4 is given by,
14) Let X denote the number of patients who experienced weight gain as a side effect in a random sample of 50.
15) The probability that 8 or fewer experienced weight gain as a side effect is given
16) The probability that 6 or more patients experienced weight gain as a side effect is
17) According to the range rule of thumb, most values should lie within 2 standard deviations from the mean. We can therefore identify "unusual" values by determining if they lie outside these limits
