A major car manufacturer wants to test a new engine to determine if it meets new air pollution standards. The mean emission, μ,

of all engines of this type must be approximately 20 parts per million of carbon. If it is higher than that, they will have to redesign parts of the engine. Ten engines are manufactured for testing purposes and the emission level of each is determined. Based on data collected over the years from a variety of engines, it seems reasonable to assume that emission levels are roughly Normally distributed with σ = 3 parts per million of carbon. What are the appropriate null and alternative hypotheses?

It is recommended that an adult drink 64 fluid ounces of water everyday Josie has already consumed 700 mL of water how many more
katen-ka-za [31]

Answer:

1.2 litres  more water should Josie drink.

Step-by-step explanation:

As given

It is recommended that an adult drink 64 fluid ounces of water everyday .

As given

1 ounce = 0.0296 litre .

Now convert 64 ounces into litre.

64 ounce = 64 × 0.0296

                = 1.9 litres (Approx)

As

1 litre = 1000 ml

1\ ml= \frac{1}{1000}\ litre

Now convert 700 ml into litre.

700\ ml= \frac{700}{1000}\ litre

700\ ml= \frac{7}{10}\ litre

700 ml = 0 .7 litre

Thus

Recommended amount of water a adult should drink = Amount of water Josie already consumed + More water should Josie drink.

Putting the value

1.9 litres = 0 .7 litres +  More water should Josie drink.

More water should Josie drink = 1.9 - 0.7

More water should Josie drink = 1.2 litres .

Therefore 1.2 litres  more water should Josie drink.
