The marketing brochure for a travel agency shows that the standard deviation of hotel room rates for two cities is the same. Table 7is given the per day room rate in Pak Rs.

Can you reject the agency claim at α=0.05

“Marriott International announced in November 2018 that attackers had stolen data on approximately 500 million customers. The breach initially occurred on systems supporting Starwood hotel brands starting in 2014. The attackers remained in the system after Marriott acquired Starwood in 2016 and were not discovered until September 2018.”(sourced from a published report) Referring to the case given, list and explain 2 steps that can help prevent data breach like this.

Create a list and rank the following products/services using intangibility. The list will rank tangible goods at the top and totally intangible services at the bottom. Briefly explain each category as well.

Exercise 5A-2 Least-Squares Regression [LO5-11]

Bargain Rental Car offers rental cars in an off-airport location near a major tourist destination in California. Management would like to better understand the variable and fixed portions of it car washing costs. The company operates its own car wash facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the variable portion of its car washing costs relates to the number of rental returns. Accordingly, the following data have been compiled:

Exercise 5A-2 Part 2

2. Using least-squares regression, estimate the variable cost per rental return and the monthly fixed cost incurred to wash cars. (Round Fixed cost to the nearest whole dollar amount and the Variable cost per unit to 2 decimal places.)

Virtual Safari is an augmented reality game similar to Pokémon Go.

A virtual jungle is populated by several kinds of agents: hunters (equipped with a smart phone containing a GPS device), monster factories, and ammo factories.

Agents have locations. These locations correspond to actual locations on a Google Map.

As a hunter moves, his location is updated. All nearby factories are displayed.

If a hunter is very near an ammo factory, he may request and receive 10 bullets (per hour) or he may purchase any number of bullets. (When this happens the hunter's account is debited.)

If a hunter is very near a monster factory, the factory waits a random time interval, spawns a monster, and then displays it to all very near hunters.

A monster has a type. The type of the monster tells the monster's name (e.g., Charmander, Squirle, Metapod) and integer value. The bigger the value, the harder it is to kill that type of monster.

Elite factories produce high-value types of monsters. They are rare and produce monsters infrequently.

A hunter can shoot a bullet at a monster. If enough bullets hit the monster, the monster is killed and added to the hunter's trophy room. The hunter's status is the sum of the values of all monsters in his trophy room.

1) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 63women over the age of 50 used the new cream for 6 months. Of those 63women, 36 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60% of women over the age of 50?

2) A survey of 1325 people who took trips revealed that 140 of them included a visit to a theme park. Based on those survery results, a management consultant claims that less than 12% of trips include a theme park visit. Test this claim using the ?=0.01 significance level.

The test statistic is ?

The critical value is?

3) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 54 women over the age of 50 used the new cream for 6 months.
