Question

the cargo loads that niels transports in his truck have a mean weight of 42,000 lb with a standard deviation of 1,500 lb. what will be the mean and standard deviation of the distribution of weights in kilograms? 1 lb approximately equals 0.45 kg.

Explanation:

Step1: Convert the mean weight

To convert the mean from pounds to kilograms, multiply the mean in pounds by the conversion factor.
$42000\times0.45$

Step2: Calculate the new mean

$42000\times0.45 = 18900$ kg

Step3: Convert the standard - deviation

To convert the standard deviation from pounds to kilograms, multiply the standard deviation in pounds by the conversion factor.
$1500\times0.45$

Step4: Calculate the new standard - deviation

$1500\times0.45=675$ kg

Answer:

Mean: 18900 kg, Standard deviation: 675 kg
