We have a herd of dairy cattle and we are trying to improve our conception rate while maintaining high milk production. We have genotyped our cows to select them for high conception rate. The A allele is associated with high fertility. Below is a table for 10 of our cows where we have the fertility genotype and their milk production: 1. Cow Days to conception Milk production 22,900 23,500 22,800 21,000 24,000 22,500 23,750 21,000 24,500 22,000 1 4 6 9 10 a. What is the mean for milk production and days to conception? (1 pt) b. What is the variance for milk production and days to conception? (1 pt) C. What is the standard deviation for milk production and days to conception? (2 pts) d. What is the covariance of milk production and fertility? (2 pts) e. What is the correlation of fertility and milk production? (2 pts) f. What is the regression of milk production (y) on fertility (x)? In other words, for every unit change in days to conception, how much does milk production increase? (2 pts)
