Suppоse yоu hаve the vаlues listed belоw for points scored by plаyers A and B. -Player 1: 12, 14, 16, 18 -Player 2: 12, 14, 14, 16 Calculate the following: 1) Player 1 & Player 2 mean (1.5pts) 2) Player 1 standard deviation (SD) (3pts) 3) Player 1 standard error (SE) (1.5pts) 4) Player 1 95% confidence interval (1pt) 5) Effect size difference between Player 1 & 2 (assume the SD is calculated as the simple average of the 2 means) (2pts) 6) What is the 'size' of the effect? Small, medium, or large? (1pt) *No need to calculate SD for player 2. For this question assume SD for Player 2 is equal to the SD for Player 1. *MathTip: The numerator of the fraction basically asks for the 'sum of squares' of the difference between the mean and the individual values. Get this sum. The denominator is simply the sample size minus 1. Divide the numerator value by the denominator value. Then get the square root of the fraction (numerator divided by denominator). The correct SD value is >1 and
Genetic cоunseling prоblem: (Questiоn 24-27) These questions аre bаsed on your prepаration question about inheritance patterns for two genes with disease-associated variants. Information on these human genes and the scenario is provided below. Again, assume, as appropriate, that crossing-over and recombination occur and that all cases of meiosis complete without error. If calculating the rate of recombination, z = distance between genes in base pairs/100,000,000. Gene name PMP22: Genomic location: Chromosome 17, base pairs 15,229,779 to 15,265,326 Codes for a myelin sheath protein essential to neuron functioning. A variant of the gene is associated with Charcot-Marie-Tooth Disease Type 1A (CMT), which involves impairment of the peripheral nervous system. The degree of symptoms varies and life expectancy is not affected. The disease-causing allele is dominant. Designate alleles as “A” (disease causing, dominant) and “a” (normal, recessive) Gene name BRCA1: Genomic location: Chromosome 17, base pairs 43,044,295 to 43,170,327 Encodes for a protein that helps to monitor DNA damage and acts as a tumor suppressor gene. Mutations of this gene are associated with a much higher risk of breast cancer. The normal allele shows incomplete dominance, meaning the heterozygote genotype yields a mid-level cancer risk. Designate alleles as “B” and “b”, where “BB” has no increased risk, “Bb” has a mid-level risk, and “bb” has the highest breast cancer risk. As a genetic counselor, you are working with Maurice and Alec, a couple who want to have kids. They have a long-term friend, Marcy, who will carry the baby, and one of them will contribute sperm for intrauterine insemination (IUI). Both men have a history of breast cancer in their families and both have symptoms of CMT, therefore they are seeking your help to decide who will be the biological parent in order to minimize the chances of passing on deleterious mutations. Here is the genetic information you have for each individual: Marcy has genotype aaBB. Maurice has CMT (with one copy of the disease-causing allele) and one copy of the BRCA1 mutation gene. One of his parents had the genotype AAbb. Alec also has CMT and one copy of the BRCA1 mutation gene. One of his parents did not have CMT but had a high risk of cancer.
