Question

Section 3: Short computations (5 points each) A) The correlation () between oscillation speed and distance travelled in a sample of 48 lying snakes is 0.24. Is this significant? Give the approximate range of the p-value for this correlation. B) In a microarray study of yeast, you test for an association between gene expression level and growth rate for each of 5452 genes. At a p-value threshold of 0.001, you find 854 genes whose expression is significantly associated with growth rate. What is the false discovery rate (FDR? CA population of ladybugs consists of 10% ladybugs with no spots, 30% with two spots, and 60% with more than two spots (many-spot). What is the probability that three randomly caught ladybugs will include one no-spot, one two-spot and one many-spot? D)Body temperature of healthy humans has a normal distribution with mean 98.3 °F and variance 0.537 "F?, What is the p and 99°F?
