The approximate percentage of final exam scores that are less than 54 is 15.87%.
How to calculate the percentageBased on the information, the random sample of Statistics final exam scores has a sample mean of x¯=65 and the sample standard deviation is s=11.
Therefore, the approximate percentage of final exam scores that are less than 54 will be:.
P(X < 54) = P (Z < 54 - 65/11)
= P(Z < -11/11)
= P (Z < -1)
= 0.1587.
Therefore, the approximate percentage of final exam scores that are less than 54 is 0.1587 or 15.87%.
