Five loci defined by microarrays are known to contribute to meat quality in cattle. These can be tested using microarrays. Premium meat quality occurs when eight or more of the alleles at these five loci are of the “contributing” variety. An uppercase letter indicates a contributing allele and lowercase letter indicates a noncontributing allele. One can determine the genotype of cattle with a microarray. If the following genotypes of a cow and a bull (respectively) are crossed, what is the probability the first offspring will have eight or more contributing alleles? Assume all loci are autosomal and independent. AaBbccDDEe × AaBBCCDdEe

If SSBetween = 225.31 and there are four groups in the study with 10 cases per group, MSBetween = :

According to the National Health and Nutrition Examination Survey (NHANES) sponsored by the U.S. government, a random sample of 712 males between 20 and 29 years of age and a random sample of 1,001 males over the age of 75 were chosen and the weight of each of the males were recorded (in kg). Do the data provide evidence that the younger male population weighs more (on average) than the older male population? Use “Y” for ages 20-29 and “S” for ages 75+. It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0.   a)Suppose the test statistic is t = 2.398. What is the associated p-value? Group of answer choices 0.001 < p-value < 0.002 0.005 < p-value < 0.01 0.01 < p-value < 0.02 0.0005 < p-value < 0.001   b) Suppose the p-value is 0.02 < p-value < 0.04. At α = 0.10 what is the appropriate conclusion to make? Group of answer choices Fail to reject H0 and conclude that the mean weight of all males ages 20-29 is greater than the mean weight of all…

Question 7                               Consumer report uses a survey of readers to obtain customer satisfaction ratings for the nation's largest retailers. Each survey respondent is asked to rate a specified retailer in terms of six factor: quality of products, selection, value, check out efficiency, service and store layout . Any overall satisfaction score summarizes the rating for each respondent with 100 meaning the respondent is completely satisfied in terms of all six factors. Sample data respresentative of independeent samples of Target and Walmart customers are show below.                                  Target  Walmart             n - 25 n = 30              mean = 79 mean = 71                             part a               Formulate the null and alternative hypoteses to test whether there is a difference between the population mean customer satisfactions scores for the two retailers                                 part b               Assume…

It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0. A) What are the correct null and alternative hypotheses? B)What is the parameter of interest?   The difference between the mean weight of all males ages 20-29 and the mean weight of all males ages 75+ The mean weight (in kg) The difference between the mean weight of the sample of males ages 20-29 and the mean weight of the sample of males ages 75+ The mean difference between the weights of males ages 20-29 and males ages 75+   c)Is the randomness condition met for…
