An agricultural researcher plants 25 plots with a new variety of corn. The average yield for these plots is 150 bushels per acre. Assume that the yield per acre for the new variety of corn follows a Normal distribution with unknown mean μ and that a 95% confidence interval for μ is found to be 150 ± 3.29. Which of the following options gives the correct notation for and value of the point estimate? A) n=25
B) μ= 150
C) x=150
D) =150
E) P=150

C is the correct option.

Step-by-step explanation:

Confidence interval for population mean:

, where = Sample mean

E = Margin of error

Given confidence interval : 150 ± 3.29

Here ,

Since the sample mean is the best estimate for the population mean.

Thus, the correct notation is

i.e. C is the correct option.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
