Example 2.9 Suppose that a particular trait of a person (such as eye coloror left handedness) is classified on the basis of one pair of genes and supposethat d represents a dominant gene and r a recessive gene. Thus a person withdd genes is pure dominance, one with rr is pure recessive, and one with rdis hybrid. The pure dominance and the hybrid are alike in appearance. Chil-dren receive one gene from each parent. If, with respect to a particular trait,two hybrid parents have a total of four children, what is the probability thatexactly three of the four children have the outward appearance of the dominantgene?

A computer store sells three types of microcomputers, brand A, brand B, and brand C. Of the computers they sell, 65% are brand A, 30% are brand B, and 5% are brand C. They have found that 15% of the brand A computers, 10% of the brand B computers, and 5% of brand C computers are returned for service during the warranty period. If a computer is returned for service during the warranty period, what is the probability that it is a brand A computer? A brand B computer?

A poll released this week found that in a random sample of registered voters, 60% indicated that they think a fenmale "will run" for the presidency, 30% said a female “will not run," and 10% had “no opinion." When asked their opinions on whether or not a female could be elected, 66% of those who said a female "will run" thought a female could be elected; 25% of those who thought a female "will not run" thought a female could be elected; whereas, 20% of those who had no opinion said 4. that a female could be elected. а. [2] What percentage of registered voters (in this sample) thought that a female could be elected? [2] Given that a person thought that a female could be elected, what is the probability that this person said a female "will not run" for the presidency? b.

Childhood maltreatment is thought to be linked to adult narcissistic traits. In particular, it isthought that the more severe the childhood maltreatment, the more a person would sufferfrom the vulnerable form of narcissism. Individuals with this type of personality disorder displayattention seeking behaviors, lack empathy, are resentful, have an inferiority complex, and viewcriticism as a personal attack. As a result, these individuals can be very resentful and vindictivetowards others. A research clinician has a sample of n=20 patients who have suffered extremechildhood maltreatment and agree to be assessed on a well-known interval scale for vulnerablenarcissism. For the general population, scores on the vulnerable narcissism scale are normallydistributed with a µ = 25 and s=4. The sample of patients score an average of M=29.Can the research clinician conclude that the sample of patients who have experiencedchildhood maltreatment score significantly higher in vulnerable narcissism…
A consumer products testing group is evaluating two competing brands of tires, Brand 1 and Brand 2. Tread wear can vary considerably depending on the type of car, and the group is trying to eliminate this effect by installing the two brands on the same 10 cars, chosen at random. In particular, each car has one tire of each brand on its front wheels, with half of the cars chosen at random to have Brand 1 on the left front wheel, and the rest to have Brand 2 there. After all of the cars are driven over the standard test course for 20,000 miles, the amount of tread wear (in inches) is recorded, as shown in the table below. Car 1 2 3 4 5 6 7 8 9 10 Brand 1 0.46 0.59 0.48 0.62 0.40 0.42 0.59 0.54 0.42 0.42 Brand 2 0.32 0.41 0.37 0.43 0.24 0.49 0.51 0.44 0.44 0.44 0.14 Difference (Brand 1- Brand 2) 0.18 0.10 0.11 0.19 0.16 -0.07 0.08 -0.02 -0.02 Send data to calculator V Based on these data, can the consumer group conclude, at the 0.05 level of significance, that the mean tread wears of the…

An online clothing retailer is testing a new e-mail campaign by sending one version of the e-mail with the word “free” in the subject line (version A) to a group of 1,500 customers and another version of the e-mail with word “discount” in the subject line (version B) to a different group of 1500 customers. After tracking the responses to the two versions of the e-mail advertising, the retailer finds that 75 responded to version A and 105 responded to version B. At 0.05 significance level, can it be concluded that the response rate for version B is higher than the response rate to version A What is your decision?

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?

The Coca-Cola Company introduced New Coke in 1985. Within three months of this introduction, negative consumer reaction forced Coca-Cola to reintroduce the original formula of Coke as Coca-Cola Classic. Suppose that two years later, in 1987, a marketing research firm in Chicago compared the sales of Coca-Cola Classic, New Coke, and Pepsi in public building vending machines. To do this, the marketing research firm randomly selected 10 public buildings in Chicago having both a Coke machine (selling Coke Classic and New Coke) and a Pepsi machine.

1. A realtor sells houses in three different neighborhoods in the city—A, B and C. He sells ranch style homes and two-story homes. Last year, 60% of his sales were in neighborhood A, while neighborhood B made up 25% and neighborhood C was 15% of the sales. Only 10% of the houses in neighborhood A were ranches, compared with 40% for neighborhood B and 50% for neighborhood C. Suppose we randomly select one of the homes he sold in one of these three neighborhoods. (1) What’s the probability that the home is a ranch? (Enter a decimal as your answer, round to the nearest thousandth when necessary) (2) If the home is a ranch, what’s the probability that it is in neighborhood C? (Enter a decimal as your answer, round to the nearest thousandth when necessary)
