Answer #1

Answer: According to the National Association of Theatre Owners, in 2017, the mean admission charge for a movie was $8.97. the distribution of movie admission charge is normally distributed with a standard deviation of $2.05 what is the probability that randomly selected admission is less than $8.79.

Solution:  

Mean, μ = 8.97

Standard deviation, σ = 2.05

the probability that randomly selected admission is less than $8.79.

P(X < 8.79) = P(x̄ - μ/σ < 8.79 - 8.97 / 2.05)

P(X < 8.79) = P(Z < - 0.0878)

P(X < 8.79) = 0.46502

Therefore, the probability that randomly selected admission less than $8.79 is 0.4650.
