Answer:
1.0e51
Step-by-step explanation:
Answer:
The standard error of the mean is 0.85.
Step-by-step explanation:
The given standard deviation of a population (σ) = 7.8
sample size (N) = 85
We have to find standard error of the mean.
The formula to find standard error of the mean
= (standard deviation of the distribution) / (square root of sample size)
= (σ) / (√N)
= 7.8 / (√85)
= 7.8 / 9.219544457
= 0.8460
= 0.85 (approximately taken to two decimal places)
We have got the required answer.
The standard error of the mean is 0.85.
Sorry I need to answer something so I can ask questions so I’m typing this
Area of semicircle = 1/2 x pi x radius x radius
radius of semicircle = 14/2 = 7
pi = 3.14 for this question, so
1/2 x 3.14 x 7 x 7 = 76.93
area = 76.93
