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.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
