Answer:
the probability that the average loss from fire in the sample is no greater than $275 is 0.9938
Step-by-step explanation:
given information:
mean, μ = $250
std deviation, σ = $1000
random sample, n = 10000
x = $275
P( ∠_ 275) = P(z < (z ∠ (x - μ)/(σ/√n))
= P (z ∠ (275 - 250)/(1000/√10000)
= P(z ∠ 2.5)
= 0.9938
