Question Help Last year, a person wrote 127 checks. Let the random variable x represent the number of checks he wrote in one day, and assume that it has a Poisson distribution What is the mean number of checks written per day? What is the standard deviation? What is the variance? The mean number of checks written per day is I (Round to three decimal places as needed.) The standard deviation is (Round to three decimal places as needed) The variance is (Round to three decimal places as needed) Enter your answer in each of the answer boxes

Answer 1

عدد 127 solution Here given that a person wrote 127 checks per year and no. of checks hea corote in one day then = -0.3u8 > Here you poisson (0.3u8 so, mean no. of checks per day = x=0.348 - standard deviation = 5=50 3u8 = 0.5899 -0.590 - Variance = x= 10:3u8 365
