Chapter 11, Problem 40PS

A hotel wanted to develop a new system for delivering room service breakfasts. In the current system, an order from is left on the bed I each room. If the customer wishes to receive a room service breakfast, he or she places the order from on the doorknob before 11 P .M . The current system requires customer to select a 15-minute interval for desired delivery time ( 6 : 30 6 : 45 A .M ., 6 : 45 7 : 00 A .M ., etc . ) . The new system is designed to allow the customer to request a specific delivery time. The hotel wants to measure the difference (in minutes) between the actual delivery time and the requested delivery time of room service orders for breakfast. (A negative time means that the order was delivered before the requested time. A positive time means that means that the order was delivered after the requested time.) The factor included were the menu choice (American or Continental) and the desired time period time period in which the order was to be delivered (Early Time Period [ 6 : 30 8 : 00 A .M . ] or Late Time Period [ 8 : 00 9 : 30 A .M . ] ) . Ten order for each combination of menu choice and desired time period were studied on a particular day. The day, stored in Breakfast: are as follows:

At the 0.05 level of Significance,

a. is there an interaction between type of breakfast and desired time?

b. is there an effect due to type of breakfast?

c. is there an effect due to desired time?

d. Plot the mean delivery time difference for each desired time for each type of breakfast.

e. On the basis of the results of (a) through (d), what conclusions can you reach concerning delivery time difference? Discuss.

Find binomial probability if: x = 8, n = 10, p = 0.7 x= 3, n=5, p = 0.3 x = 4, n=7, p = 0.6 Quality Control: A factory produces light bulbs with a 2% defect rate. If a random sample of 20 bulbs is tested, what is the probability that exactly 2 bulbs are defective? (hint: p=2% or 0.02; x =2, n=20; use the same logic for the following problems) Marketing Campaign: A marketing company sends out 1,000 promotional emails. The probability of any email being opened is 0.15. What is the probability that exactly 150 emails will be opened? (hint: total emails or n=1000, x =150) Customer Satisfaction: A survey shows that 70% of customers are satisfied with a new product. Out of 10 randomly selected customers, what is the probability that at least 8 are satisfied? (hint: One of the keyword in this question is “at least 8”, it is not “exactly 8”, the correct formula for this should be = 1- (binom.dist(7, 10, 0.7, TRUE)). The part in the princess will give you the probability of seven and less than…

Selon une économiste d’une société financière, les dépenses moyennes pour « meubles et appareils de maison » ont été moins importantes pour les ménages de la région de Montréal, que celles de la région de Québec. Un échantillon aléatoire de 14 ménages pour la région de Montréal et de 16 ménages pour la région Québec est tiré et donne les données suivantes, en ce qui a trait aux dépenses pour ce secteur d’activité économique. On suppose que les données de chaque population sont distribuées selon une loi normale. Nous sommes intéressé à connaitre si les variances des populations sont égales.a)    Faites le test d’hypothèse sur deux variances approprié au seuil de signification de 1 %.
