A survey of 1000 grocery shoppers indicated that 24% of males and 57%of females make an impulse purchase every time they shop. Assume that the survey consisted of 500 males and 500 females. Complete parts (a) and (b) below. Question content area bottom Part 1 a. At the 0.01 level of significance, is there evidence of a difference in the proportion of males and females who make an impulse purchase every time they shop?

- The table shows data from a stadium concession stand, representing average temperature (x) in degrees Fahrenheit and the number of popsicles sold (y). A 4-column graph with 6 rows. Column 1 is labeled x with entries 65, 72, 85, 88, 92, sigma-summation x = 402. Column 2 is labeled y with entries 22, 25, 52, 65, 78, sigma-summation y = 242. Column 3 is labeled x squared with entries 4,225, 5,184, 7,225, 7,744, 8,464, sigma-summation x squared = 32,842. Column 4 is labeled x y with entries 1,430, 1,800, 4,420, 5,720, 7,176, sigma-summation x y = 20,546. Which regression equation correctly models the data? y = 0.60x – 17 y = 0.60x – 0.16 y = 2.09x – 114 y = 2.09x – 120Let Xi be arandom sample from U(0,1)prove that Xn’ convarges in probability to 0.50Random samples of size n = 3 are drawn from a finite population consisting of the number 5, 6, 7, 8 and 9. d.

- Taking expectation of a Wiener process wich is normally distrubuted with n(0,1) what is the value of that expectation?Machine X use X-rings to contain burning fuel in the combustion chamber. For aspecific model of machine X, it uses three X-rings (X1, X2, and X3). For a successfulcombustion experiment, there should be no fuel leakage and for that X1 must functionwith at least one of the other X-rings.Assuming that the X-rings behave independently of one another, that each X-ring hasa 0.9 probability of working. Construct a tree diagram to represent the information above.Women executives A company is criticized because only13 of 43 people in executive-level positions are women.The company explains that although this proportion islower than it might wish, it’s not surprising given thatonly 40% of all its employees are women. What do you think? Test an appropriate hypothesis and state your con-clusion. Be sure the appropriate assumptions and condi-tions are satisfied before you proceed.
- Consider a Poisson process of intensity λ > 0 events per hour. Suppose that exactly one event occurs in the first hour. Let X be the time at which this event occurs, measured in hours (so that the possible values of X are the reals in the interval [0, 1]). (a) What is P (0 ≤ X ≤ a) for a ∈ [0, 1]? (Of course, we are conditioning on exactly one event occurring in the first hour, as described.) Hint: Consider the number of events that occur in [0, a] and in (a, 1], similar to question #5 on the previous homework. (b) What is the distribution of X, under the same conditions? (You might want to wait until Monday’s class after break to do this last part.)Regarding the four conditions required for using the pooled t-procedures: a. what are they? b. how important is each condition?Prove that cov(X, Y) = cov(Y, X) for both discreteand continuous random variables X and Y.
