The accompanying table contains a food critic's ratings for food, décor, service, and cost per person for a sample of 50 restaurants located in a city and 50 restaurants located in suburban areas outside the city. you want to study differences in the cost of a meal between restaurants in the city and suburban areas and also want to be able to predict the cost of a meal. completely analyze the data.

test for the difference between the mean cost of a city meal and the mean cost of a suburban meal, using α = 0.05.

choose an appropriate set of hypotheses, where mu 1μ1 is the mean cost of a meal in the city and mu 2μ2 is the mean cost of a meal in the suburbs.

a. h0 : h0: μ1 ≠ μ2 h1 : μ1 = μ2

b. h0 : μ1 = μ2 h1 : μ1 ≠ μ2

c. h0: μ1 > μ2 h1: μ1 = μ2

d. h0: μ1 = μ2 h1 : μ1< μ2

Option B)

Step-by-step explanation:

We are given the following information in the question:

We want to study differences in the cost of a meal between restaurants in the city and suburban areas.

We have to perform a hypothesis test for the difference between the mean cost of a city meal and the mean cost of a suburban meal, using α = 0.05.

First, we design the null and the alternate hypothesis

The null hypothesis states that there is no significant difference mean cost of a city meal and the mean cost of a suburban meal that is they are the same.

The alternative hypothesis states that there is a significant difference mean cost of a city meal and the mean cost of a suburban meal that is they are not the same.

your exact question is kind of difficult to understand, so maybe an example will explain what you're supposed to do? i'll work through the first problem on the worksheet.

suppose you have a tray of 652 brownies, and you have 5 friends that you want to feed without picking favorites. how many brownies can you dole out to each of your friends in equal amounts? how many will be left over for you to eat?

what you're doing here is finding a way to arrange the number 652 as the sum of integer multiple of 5 and some remainder:

here ("q" for quotient) is the number of brownies each of your friends get, and is the remainder. that's the basic idea behind division.

we break up the number 652 into parts so that the leading digit stands on its own:

652 = 600 + 52

first we check if it's possible to hand out exactly 100 brownies to each friend. with 5 friends, this means we want to know if we can take out 500 brownies from the tray. we can do this 1 time because we have 600 brownies to take from, and when we do that we're left with 100 + 52 brownies to divvy up. so we know that

652 = 1*500 + 152

next we want to know if it's possible to hand out exactly 10 brownies per friend. if we can, we have to remove 50 brownies from the tray each time until we can't. we have 152 brownies left, and we know that 3(50) = 150, so

152 = 3*50 + 2

now we have 2 brownies left in the tray. is it possible to hand 1 out to each of your 5 friends? no, you'd need a minimum of 5 brownies to do that. so the last 2 are yours.

putting everything together, we found that

652 = 1*500 + 3*50 + 2

and we can rearrange this to write

652 = 5*100 + 5*30 + 2

652 = 5(100 + 30) + 2

652 = 5*130 + 2

so and .

you might be more accustomed to the table depicting the algorithm. that's just a compact way of organizing what we've done above. you can consult the image i've attached below.
