A magazine collected the ratings for food, decor, service and the cost per person for a sample of 102 restaurants. They combined the ratings to create a summated rating and used that to predict the cost of a restaurant meal. The data are modeled by Y₁ = -25.002+1.0004X₁, where X; is summated ratings and Ŷ¡ is meal cost. For these data, Syx = 8.731, X = 62.59, and h; = 0.026985 when X = 54. Complete parts (a) through (c). a. Construct a 90% confidence interval estimate of the mean cost of a meal for restaurants that have a summated rating of 54. 26.639 ≤HY|X=X₁ ≤ 31.40 (Type integers or decimals. Round to three decimal places as needed. Use ascending order.) b. Construct a 90% prediction interval of the cost of a meal for an individual restaurant that has a summated rating of 54. 0.004sYx=545 (Type integers or decimals. Round to three decimal places as needed. Use ascending order.) S

An automobile manufacturing plant produced  37  vehicles today:  17  were sedans,  11  were vans, and  9  were trucks. Plant managers are going to select two of these vehicles for a thorough inspection. The first vehicle will be selected at random, and then the second vehicle will be selected at random from the remaining vehicles. What is the probability that two vans will be selected?   Do not round your intermediate computations. Round your final answer to three decimal places.

Hi i am confused on how this is the answer the solution was cut off

First picture is the problem and second question is the question to the problem. Please state answer from the drop down choices.

i think the answer above is wrong

When I put 2+1 or 3 as the answer it said I got the question wrong? Did I perhaps misread your response?

How do you do a question like this

Hello. Can you please in words explain how you got the answer that you did?
