The vehicle speeds at a particular interstate location can be described by a normal curve. the mean speed is 64 mph, and the standard deviation is 7 mph. what proportion, p of vehicle speeds at this location are faster than 71 mph? (round the answer to four decimal places.)

The speed is normally distributed with mean μ=64 and standard deviation σ =7. Use the transformation for calculating the probability. This value is called Z-score.

The Z score is .

Refer to the standard normal distribution table.

The probability

Thus, the proportion of the vehicles that are travelling faster than 71 mph is .

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
