You want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicle right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 9 mph. Determine the real limits of 9. When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 120 pounds? When measuring weight on a scale that is accurate to the nearest 0.5 pound, what are the real/limits for the we.ght of 187 pounds?

Answer:

First Question

lower limit of 9 mph  [tex]j =  8.5 \  mph[/tex]

upper  limit of 9 mph [tex]q =  9.5 \  mph[/tex]

Second Question

lower limit of 120 pounds is  [tex]i =  119.9 \  pounds[/tex]

upper limit of 120 pounds is  [tex]l =  120.1 \  pounds[/tex]

Third  Question

lower limit of 187 pounds is  [tex]a =  186.75 \  pounds[/tex]

upper limit of 187 pounds is  [tex]b =  187.25 \  pounds[/tex]  

Step-by-step explanation:

From the question we are told that

  The amount of beer administered is  three 12-ounce beers

  The  amount of coffee administered is  two cups of coffee

  The  speed limit is   60-mph

  The smallest unit of scale is  1 mph

  The first subject scores 9 mph

Generally given that the smallest unit of scale is  1 mph then the deviation of  9 mph will be by [tex]\frac{1}{2} \ mph[/tex]

Hence the lower limit of 9 mph is

    [tex]j =  9 - 0.5[/tex]

    [tex]j =  8.5 \  mph[/tex]

And  the upper  limit of 9 mph is

    [tex]q =  9 + 0.5[/tex]

    [tex]q =  9.5 \  mph[/tex]    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by  [tex]\frac{1}{0.2} \ pounds[/tex]

Hence the lower limit of 120 pounds is

    [tex]i =  120 - 0.1[/tex]

    [tex]i =  119.9 \  pounds[/tex]

And  the upper  limit of 120 pounds is

    [tex]l =  120 + 0.1 [/tex]

    [tex]l =  120.1 \  pounds[/tex]    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then  187 pounds will deviate by  [tex]\frac{1}{0.5} \ pounds = 0.25 \ pounds  [/tex]

Hence the lower limit of 120 pounds is

    [tex]a =  187 - 0.25[/tex]

    [tex]a =  186.75 \  pounds[/tex]

And  the upper  limit of 120 pounds is

    [tex]b =  187 + 0.25 [/tex]

    [tex]b =  187.25 \  pounds[/tex]      

Caffeine migrates the effects of alcohol.

Caffeine being a drug in itself is able to remove the effects of alcohol drugs. In order to study the effects of drinking coffee can be used to cure and treat the patients suffering.

Thus caffeine has more medicinal usage.

  • The study administered to the subject that drink coffee equivalent to three 12 ounces of beer was taken in 2 cups of coffee. The subjects were asked to do driving takes which has some mixed reactions.
  • The goal was to find a cause-and-effect relationship. The study proves that the caffeine kept them more awake as per the use of alcohol of the beer.
  • Hence as per the effect of chemicals, the effects of weights increased. Thus was able to migrate the reaction time.
