Answer:
t distribution behaves like standard normal distribution as the number of freedom increases.
Step-by-step explanation:
The question is missing. I will give a general information on t distribution.
t-distribution is used instead of normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.
Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.
Step-by-step explanation:
Convert the speeds of Amir and Ryder to meters per second (m/s).
Amir:
8260 mm/s = 8.260 m/s
Ryder:
930 cm/s = 9.30 m/s
9.30 m/s > 8.260 m/s, so:
Ryder ran approximately 1 meter per second faster than Amir.
The answer would be A because you would take all of your answers and 1 by 1 multiply it by0.35 and it will give you the answer of $330.43
