Answer:
c. Skewed-right with a mean of $5.25 and a standard error of$0.28
Step-by-step explanation:
As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.
Now, We know that if standard deviation = σ
then, standard error = 
As, we have standard deviation = $2.80
then standard error will be
⇒ Standard error = $0.28
Hence, Option (c) is the correct option.
The formula for finding the length is
