Hi,

Where did -0.675 came from?

Problem was previously submitted via Bartbly.

ty,

Chapter 7 Question 2.
Being curious about land holdings size,
Harry found something interesting to his surprise,
The average land holding is about 180 acres for each farm
And a standard deviation of 75 acres does not harnm
He asked a group of farmers totaling forty-two
To check these facts and to calculate, too
What is the distribution of the acreage in his sample?
To find the IQR he has information, ample!
Answer the following questions:
a. X is the size of a farm in the US (answer "True" or "False"):
b. X is normally distributed with a mean of
acres and standard error of
acres.
c. The IQR for X is
acres.
