A bus company has records showing that its buses arrive on time 95% of the time.Suppose the company operates 65 bus trips each day. The CEO has asked for theprobability that 60 or more of these buses arrive on time.a) Use the binomial distribution todetermine the probability that 60 ormore buses arrive on time.b) Could this distribution bereasonably modelled using a normalapproximation? Give reasons for youranswer.c) Determine the mean and standarddeviation of the normal approximation.d) Use the normal approximation todetermine the probability that 60 ormore buses arrive on time.

a) To use the binomial distribution to solve this problem, we will calculate the probability of each…

Please show work in excel Katie likes to shop at VONS. For each trip to the retail store, Katie spends an average of 44 mins with a standard deviation of 10 mins. The length of time spent in the store is normally distributed. Find the probability distribution that the shopper will be in the store for more than 30 minutes. Find the probability distribution that the shopper will be in the store between 35 minutes and 40 minutes. If 300 shoppers enter the store how many shoppers would you expect to be in the store for each time interval listed above (a,b). Interpret the results from a-c.
