Answer:
Option C) 0.830
Step-by-step explanation:
We are given the following in the question:
The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean
.
Sample size, n = 25
Sample mean,
= 69.72 inches
Standard deviation,
= 4.15 inches
We have to find the standard error of
.
Standard error =

Thus, the standard error of
is 0.83 inches.
The correct answer is
Option C) 0.830
Answer:
sqrt(-3)
Step-by-step explanation:
solve using sqrt( b^2 - 4ac)
substitute values from original equation to find discriminant
I think the answer is 30, because if 134 +16 is 5 times the number of books Beezus reads, than just divide by 4 for the answer of 30
