In a game show, a contestant is presented with three doors: Door A, Door B, and Door C. Behind one of these doors is a car, and behind the other two are goats. The contestant picks one door, say Door A, and the host, who knows what's behind each door, opens another door, say Door B, revealing a goat. The contestant is then given the choice to stick with their original choice (Door A) or switch to the remaining unopened door (Door C). What is the probability of winning the car if the contestant decides to switch doors?

1. The shares of the U.S. automobile market held in 1990 by General Motors, Japanese manufacturers, Ford, Chrysler, and other manufacturers were, respectively, 37%, 20%, 22%, 12%, and 9%. Suppose that a new survey of 1,000 new-car buyers shows the following purchase frequencies:
A report in the college newsletter used the registrar's database for all the students in the school to look at majors and classes being taken this semester. The report includes the sentences:
1. In a psychological study of distance perception, introductory psychology class volunteers were given either 5 or 10 extra credit points depending on their level of participation in the experiment. They walked along paths laid out along hallways in the psychology building, and were asked to judge the distance they had walked. Each path distance was between 100 and 200 feet in length, and contained from two to seven 90 degree turns. The investigators also kept track of class standing (freshman, sophomore, junior, or senior) of each participant. For each of the variables in the study, determine whether it is qualitative or quantitative. For each quantitative variable, determine whether it is discrete or continuous. For each qualitative variable, determine whether it is nominal or ordinal. [4 pts.] a. The true length of the path b. The amount of credit given to volunteers c. Class standing d. The number of 90 degrees turns 2. In a survey of exercise habits, 1500 national adults were…
250 adults are practicing every day before taking part in a high-stakes children's game. The game requires them carefully to remove a shape- either a star or an umbrella-from a sugar wafer. 30% of those who choose stars on a given day will switch to umbrellas the next day, and 20% of those who choose umbrellas on a given day will switch to stars the next day. (a) If 150 contestants practice with stars today, how many will practice with umbrellas tomorrow? (b) If the actual game is held a long time from now, what proportion of contestants do we expect will be practicing with stars each day close to then?
Suppose a consumer affairs representative for Mars Incorporated claims that M&M’s plain chocolate candies are mixed such that each large production batch has the following percentages of colored candies: 20% brown, 20% yellow, 10% red, 20% orange, 10% green, and 20% blue. To test this claim, a professor distributed small sample bags of M&M’s to students and had them count the number of candies of each color. The counts of the students were then pooled with the following results. At α=0.05, determine whether there is sufficient evidence to conclude that the percentages are different from what the representative claims. Candy Colors Brown Yellow Red Orange Green Blue Number of candies 190 185 110 168 117 189 Copy Data Step 3 of 4 : Compute the value of the test statistic. Round any intermediate calculations to at least six decimal places, and round your final answer to three decimal places.
Flowering plant species can be subject to inbreeding, through self-fertilization. Some species have adaptations that help to avoid this inbreeding, through asymmetric flower structures. If the flower structures are “right-handed”, then a pollinator visiting the right-handed flower will get pollen on its left side, and thus, only be able to deposit the pollen on a left-handed flower that it visits later on. [Similarly, pollinator visits to left-handed plants will result in pollen deposits on right-handed plants.] You are interested in studying a particular plant species called Lupinus perennis, that demonstrates handedness, and you wish to know whether one type of handedness is more prevalent than the other (e.g., are left-handed plants more prevalent than right-handed plants?) You sample 30 L. perennis plants, and find that 20 plants are right-handed, and 10 plants are left-handed. Is one type of handedness more prevalent than the other? What is your null hypothesis? Report the…
