According to a recent Harris Poll of adults with pets, the probability that the pet owner cooks especially for the pet either frequently or occasionally is 0.24. (a) From this information, can we conclude that the probability a male owner cooks for the pet is the same as for a female owner? Explain. (b) According to the poll, the probability a male owner cooks for his pet is 0.27, whereas the probability a female owner does so is 0.22. Let’s...
11. Pet Ownership A recent random survey of households found that 14 out of 50 householders had a cat and 21 out of 60 householders had a dog. At a = 0.05, test the claim that fewer household owners have cats than household owners who have dogs as pets.
According to a recent survey of households, the poll found that 48% of the adults watching a special event on TV enjoyed the commercials more than the event itself. Consider a random sample of nine adults who watched the special event. Complete parts a through d below. 1 (3 pts) What is the probability that less than four people enjoyed the commercials more than the event? what is the probablility that exactly six or seven people enjoyed the commericals more...
According to a Gallup poll, more than half of all Americans drink at least one glass of soda per day. Suppose X is a random variable that represents the number of glasses of soda that a randomly selected American drinks each day. The probability distribution for X is given: X 0 1 2 3 4 P(X=x) .4 .33 .14 .09 .04 Given a randomly selected American drinks at least two glasses of soda each day what is the probability that...
4 Gi According to a recent poll 53 percent of Americans would vote for the incumbent president. If a random sample of 100 people results in 45 percent who would vote for the incumbent, test the claim that the actual percentage is 53 percent. Use a 0.10 significance level. (there are three correct choices in this question) SELECT ALL APPLICABLE CHOICES A) There is enough evidence to reject the Claim B) Ho p2.53 (claim) H1: P<.53 C) There is enough...
Suppose that a recent poll found that 53% of adults believe that the overall state of moral values is poor. Complete parts (a) through (c). (a) For 400 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. (b) Interpret the mean. (c) Would it be unusual if 142 of the 300 adults surveyed believe that the overall state of...
According to a recent poll, 27% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. Assume the standard deviation from the recent studies is accurate and known. According to recent studies, cholesterol levels in healthy adults from the area average about 205mg/dL, with a standard deviation of about 30mg/dL, and are roughly Normally distributed....
Java:Netbeans-Use the LinkedList class to simulate a queue, and use the add method to simulate the enqueue, and the remove method to simulate the dequeue method for a Queue. Remember to use FIFO. Need help with 0. Add New Microchips pushMicroChip(), popMicroChip() and . To simulate this, you will create a menu option 0, which will generate 100 microchip long objects, and place them into a stack of microchips. Those microchip objects will be generated by using the System.nanotime() method. ...
According to a recent poll, 29% of adults in a certain area have high levels of cholesterol.

Assume the standard deviation from the recent studies is accurate and known. According to recent studies, cholesterol levels in healthy adults from the area average about 206 mg/dL, with a standard deviation of about 25 mg/dL, and are roughly...
