Question

0. 5. Travelbyus is an internet-based travel agency wherein customers can see videos of the cities they plan to visit. The number of hits daily is a normal distributed random variable with a mean of 1,000 and a standard deviation of 2,40. What is the probability of getting more than 900 hits? Gaga

Answer 1

5)

Solution :

P(x > 900) = 1 - P(x < 900)

= 1 - P[(x - $\mu$ ) / $\sigma$ < (900 - 1000) / 240]

= 1 - P(z < 0.42)

= 1 - 0.6628

Probability = 0.3372
