Let X equal the number of bad records in each 100 feet of a used computer tape. Assume that X has a Poisson distribution with mean 2. Let W denote the number of feet before for the first bad record is found. Let Z denote the number of feet before for the second bad record is found. Let Y be the number of bad records in 50 feet.

(a) What is P(2 ≤ Y ≤ 4) ?

(b) What is the p.d.f. of W ?

(c) What is the p.d.f. of X ?

(d) Find P(W ≤ 50).

(e) Find P(50 ≤ Z ≤ 150).

Let X be a random variable that is equal to the number of times a 5 is rolled in three rolls of a fair 5-sided die with the integers 1 through 5 on the sides. What is E[X2 ]? What is E2 [X], that is, (E[X])2 ? Justify your answers briefly

Let X and Y equal the number of milligrams of tar in filtered and nonfiltered cigarettes,...

Let X and Y equal the number of milligrams of tar in filtered and nonfiltered cigarettes, respectively. Assume that ?~?(??, ?2) and ?~?(??, ?2). We shall test the null hypothesis ?0: ?? = ?? against the alternative hypothesis ??: ?? < ?? using independent random samples of sizes n = 9 and m = 11 observations from X and Y, respectively. Define the test statistic for testing the above hypothesis, and the rejection region that is associated with an ?...

Let X equal the number of telephone calls per hour that are received by 911 between...

Let X equal the number of telephone calls per hour that are received by 911 between midnight and noon. For a two-day period, researchers recorded the number of calls received in each hour. Those values were: 0, 1, 1, 1, 0, 1, 2, 1, 4, 1, 2, 3, 0, 3, 0, 1, 0, 1, 1, 2, 3, 0, 2, 2. This problem is about deciding if it looks like the Poisson distribution might be an appropriate model for X. (a)...

Let X be a Bin(100, p) random variable, i.e. X counts the number of successes in 100 trials, each having success probability p. Let Y = |X − 50|. Compute the probability distribution of Y.

Let X be the number of heads and let Y be the number of tails in...

Let X be the number of heads and let Y be the number of tails in 6 flips of a fair coin. Show that E(X · Y ) 6= E(X)E(Y ).

Let X equal the number of chocalate chips in a chocalate chip cookie. Sixty-two oberservations of X yielded the following frequencies for the possible outcomes of X: Outcome (x) 0 1 2 3 4 5 6 7 8 9 10 Frequency 0 0 2 8 7 13 13 10 4 4 1 (a) Use this data to graph the relative frequency histogram and the Poisson probability with lamda = 5.6 on the same figure. (b) Do these data seem to...

Let X equal the number of female children in a three-child family. Among students who were taking statistics, 52 came from families with three children. For these families x = 0, 1, 2, and 3 for 5, 17, 24, and 6 families, respectively. (a) Conduct a Chi-square goodness-of-fit test to test the null hypothesis that the distribution of X is B(3, 0.5) at 0.05 significance level. (b) Conduct a Chi-square goodness-of-fit test to test the null hypothesis that the distribution...

Let x be the number of different research programs, and let y be the mean number of patents per program. As in any business, a company can spread itself too thin. For example, too many research programs might lead to a decline in overall research productivity. The following data are for a collection of pharmaceutical companies and their research programs. x 10 12 14 16 18 20 y 1.9 1.4 1.6 1.4 1.0 0.7 Complete parts (a) through (e), given...

9.1-5. Let X equal the number of female children in a three-child family. We shall use a chi-square goodness-of- fit statistic to test the null hypothesis that the distribution of X is b (3, 0.5). (a) Define the test statistic and critical region, using an α = 0.05 significance level. (b) Among students who were taking statistics, 52 came from families with three children. For these families, x= 0, 1, 2, and 3 for 5, 17, 24, and 6 families,...
