Ex.1 (on Probability handout)An electronic shop receives a box of 100 electronic devices of which 10 devices have type Adefect, 8 devices have type B defect and 3 devices have both type A and B defects. If a deviceis picked at random from the box (so that each one of the 100 devices has an equal chance ofbeing picked), finda) the sample space for the experimentb) the probability that the device picked has a type A defectc) the probability that the device picked has a type B defectd) the probability that the device picked has both types of defectse) the probability that the device picked has a defectf) the probability that the device picked is free of defects

The total number of electronic devices in a box is 100.The number of type A defects is 10.The number…

20) Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 24. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 24.
A sampling distribution contains four possible values for the sample means. Three of the four probabilites are 0.17, 0.3, and 0.3. The remaining probability a) is 0.17 b) is 0.43 c) is 0.23 d) cant be determined without knowing the sample size
2.33 College smokers: At a university, 11% of students smoke.a) Calculate the expected number of smokers in a random sample of 190 students from this university (please do not round your answer): b) The university gym opens at 9 am on Saturday mornings. One Saturday morning at 8:55 am there are 22 students outside the gym waiting for it to open. Should you use the same approach from part (a) to calculate the expected number of smokers among these 22 students? No, it is unlikely that smoking habits and waking up early to go to the gym on Saturday are independent Yes, it is reasonable to believe that people who go to the gym when it first opens on Saturday mornings is a representative sample

During spring, young moose, unfamiliar with roads and traffic, are wandering around at night in a province, causing risk and road accidents. Suppose that the average number of road accidents involving moose was 4.6 per day. The government increased the number of hunting licenses and cleared brush to improve drivers' visibility. On one day after these measures were implemented, there were two road accidents involving moose. a) What would be the chance of two such accidents or fewer, assuming the government's measures were ineffective? b) Do you think the government's measures were effective? State your reasons clearly. a) The chance of two or fewer accidents is. (Round to three decimal places as needed.) b) Were the government's measures effective? O A. Since the probability of two or fewer accidents is relatively large, it appears that the government's measures were ineffective. O B. While the probability of two or fewer accidents is relatively small, it would not be particularly…
2. A manufacturer of men's underwear claims that 85 percent of the products are of the "best" quality, 10 percent are "seconds", and only 5 percent are defective. To test this claim, 500 garments selected at random are inspected; the inspection results in the respective frequencies of 440, 45 and 15. (a) Write down your null hypothesis and alternative hypothesis to test the manufacturer's claim. Let 1 = best quality, 2 = seconds, and 3 = defective. (b) Determine the critical region for this test (where you would reject the null hypothesis) for a = 0.05. (c) Perform a test to determine if the manufacturer's claim was valid or not. What conclusion do you reach (does the claim appear valid or not)?
3. The paper "Effects of Caffeine on Repeated Sprint Ability, Reactive Agility Time, Sleep and Next Day Performance"† describes an experiment in which male athlete volunteers who were considered low caffeine consumers were assigned at random to one of two experimental groups. Those assigned to the caffeine group drank a beverage which contained caffeine 1 hour before an exercise session. Those in the no-caffeine group drank a beverage that did not contain caffeine 1 hour before an exercise session. That night, participants wore a device that measures sleep activity. The researchers reported that there was no significant difference in mean sleep duration for the two experimental groups. In the context of this experiment, explain what it means to say that there is no significant difference in the group means. A) The difference in mean sleep duration for the caffeine and no-caffeine groups could have occurred by chance just due to the random assignment, assuming there is a real difference…
