Please answer in detail so that i can understand. The number of goals that J scores in soccer games that her team wins is Poisson with mean 2, while the number she scores in games that her team loses is Poisson with mean 1. Assume that J’s team wins each game they play with probability p. (a) Find the expected number of goals that J scores in her team’s next game. Suppose J’s team has just entered a tournament in...

31) A nonapeptide was determined to have the following amino acid composition: (Lys)2, (Gly)2, (Phe) 2, His, Leu, Met. The following are possible sequences for the peptide. A) G-F-K-K-G-L-M -F-H B) H-L-G-K-K-F-F-G-M C) H-L-F-G-K-K-F-M -G D) H-F-L-G-K-K-F-M-G E) M-L-F-K-F-G-G-K-H The following observations were made during sequence determination. (Hint: FDNB reacts with N-terminal amino groups and specificities of proteases listed...

sing R please, 1. Generate 5,000 iid samples from the standard normal distribution; compute the mean of these random samples. Repeat this process 100 times so you would have stored 100 sample averages. Plot the sample averages using hist() and lines(density() in R. What do you observe? 2. Compute the mean and variance of Binomial distribution with parameters m and p directly from definition...
