A purchaser of alarm clocks buys them in lots of size 10. It is his policy to inspect 3 clocks randomly from a lot and to accept the lot only if all 3 are nondefective. If 30 percent of the lots have 4 defective clocks and 70 percent have only 1, what proportion of lots does the purchaser reject?

A local superstore sells a "forget me not pill" that is suppose to help recall. I find that some of my fellow students at Cerritios and randomly divide divide them into two groups of 15 each. One group takes the actual "forget me not pill" and the other takes a placebo. Then I show them a list of 20 items and want them to remember as many as possible. The experimental group (those taking the pill) remember an average of 12.3 items from the list, with a sample standard deviation of 5.4. The control group (with placebo) remembered an average of 10.9 items, with a sample standard deviation of 4.2. Is this enough evidence to show that the "forget me not pill" improves memory?
brianna is taking part in a lottery for a room in one of the new dorms at her college. she is guaranteed a space, but se will have to draw a card randomly to determine exactly which room she will have. Each card has the name of one dorm ,x,y, OR Z AND ALSO HAS A TWO-PERSON ROOM NUMBER OR AN APARTMENT NUMBER.THIRTY PERCENT OF THE AVAILABILITY SPACES ARE IN X, 50% IN Y, AND 20% IN Z. HALF OF THE AVAILABLE SPACES ARE IN X ARE IN ROOM, 40% OF Y'S SPACES ARE IN ROOMS AND 30% OF THE SPACES IN Z ARE IN ROOMS. DRAW A PROBABILITY TREE DIAGRAM TO DESCRIBE THIS SITUATION.

Choices: 1. –0.54378 2. –1.21467 3. 1.41665 4. –2.48076 5. 3.28721 b. A value of 70 for ADHD has what corresponding value for ZADHD? Choices: 1. –0.54378 2. –1.21467 3. 1.41665 4. 2.48076 5. 3.28721 c. What is true of a score of 70 for ADHD? Choices: 1. It falls within ±2 SD of the mean and is thus likely to be due to chance 2. It falls within ±2 SD of the mean and is thus not likely to be due to chance 3. It falls outside ±3 SD of the mean and is thus likely to be due to chance 4. It falls outside ±3 SD of the mean and is thus not likely to be due to chance
One game at a carnival is called “Duck Pond.” This game consists of a large number of ducks that arefloating through an oval-shaped trough. A sign claims that 20% of the ducks have a blue dot on thebottom of them, 20% have a red dot, 20% have a green dot, 20% have a yellow dot, and 20% have anorange dot. Players pay to select one duck, show the color to the game attendant, replace the duck, spinaround once, and then select a second duck. If the dot on the bottom of the second duck matches the dotthat was on the bottom of the first duck, the player wins. Otherwise, the player loses. a) Are the events “color of the first duck” and “color of the second duck” independent? Explain. b) You want to perform a simulation to estimate the probability of winning this game, assuming theduck colors are distributed as claimed. Describe how you could use a table of random digits tocarry out this simulation without needing to skip any digits. c) Perform 10 trials of the simulation described in part (b)…

d. So that if two of the voluntéers khow eacil groups. 9. An experiment was conducted to see if advertisements affect the choice of snack a person cats. Twenty teenage volunteers were assigned randomly to two groups and watched a television program. One group of voluntcers watched a program with no ads and the other group watched the same program, but with ads about healthy snacks. After thc program, the teenagers were offered healthy and unhcalthy snacks. The proportion of teenagers choosing healthy snacks in the group that watched the program with the ads was larger than the proportion of teenagers choosing healthy snacks that watchcd the program without ads, and the difference was statistically significant. What does it mean that the difference was statistically significant? The observed difference in the proportion of teenagers choosing healthy snacks in the two groups is so large that it is unlikely to occur only as a result of random assignment to the groups, so the ads seem to…

Suppose we examined medical records of 500 individuals admitted to the hospital, and we cross-classified them by whether they had lung disease or some other disease and the number of cigs they smoked daily. The individuals in the sample were distributed as follows 1.What proportion of the sample both had lung cancer and smoked 25 or more cigs per day? 2.Of all individuals who had lung cancer, what proportion smoked fewer than 25 cigs per day? 3.What proportion of individuals in the sample smoked fewer than 25 cigs per day?

A quality control marketing manager orders parts and the parts are shipped in lots of sizes 15. When lots arrive, the quality manager randomly inspect 4 parts from a lot. The lot is rejected if at least one of the parts is defective. Of all lots of size 15 that arrive, 20% are have 5 defective parts and 80 percent have 2 defective parts. What proportion of lots are rejected by the manager?
