Question

You should use R for # 1,2,3,5. Question #4: R is not required. Include the R commands in your HW 4 R file submitted in canvas. For the .pdf, include all answers and the explanation in 4d. Note The root names for the distributions in R for this assignment: Binomial binom Exponential exp Gamma gamma Normal norm Poisson pois Each root must be prefixed by one of the four letters p, d, q, r. For help in R on a distribution, you can select any one of the prefixes. For example: ?pgamma 1. (12 points) According to a recent survey, one in four fear catching COVID-19 at work. Let random variable X denote the number of employees who fear catching COVID-19 at work out of 30 employees. Then X follows a binomial(n, p) distribution. (a) Find the values of n and p. (b) What is the probability that 10 or more of the 30 employees fear catching COVID-19 at work? (c) What is the probability that 5 or 6 of the 30 employees fear catching COVID-19 at work?
