(Give answer correct to at least one decimal place.) standard deviationL What is the variance in the number of yellow eggs in samples of size 66? variance Question & Points possible 1 to calculate the answer using ot least 5 decimal ploces, then glve answer correct to at least one decimal place This is attempt 2 of 3. A company prices its tornado insurance using the following assumptions: In any calendar year, there can be at most one tornado. In any calendar year, the probability of a tornado is 0.11 Type here to search

Explanation / Answer

Solution:- Given that p = 0.30, n = 66

=> Mean = n*p = 66*0.30 = 19.8 (rounde to one decimal)

=> standard deviation = sqrt(n*p*q) = sqrt(66*0.3*0.7) = 3.7229 = 3.7 (rounde to one decimal)

=> Variance = n*p*q = 66*0.3*0.7 = 13.86 = 13.9 (rounde to one decimal)
