Answer:
1514
Step-by-step explanation:
Answer:a. μ = 9.667 hours
b. σ = 1.972 hours
c. SE = 0.805 hour
Sample size (n) = 6
Sample data (xi) = 10, 8, 9, 7, 11, 13
a. Mean time spent in a week for this course by students:
Sample mean is given by:
Mean time spent in a week per student is 9.667 hours
b. Standard deviation of the time spent in a week for this course by students:
Standard deviation is given by:
c. Standard error of the estimated mean time spent in a week for this course by students:
Standard error is given by:
A(-1,3), B(-2,5)
Slope equation : (y₂-y₁) / (x₂-x₁)
Plug in the values into the equation.
AB = (5 - 3) / (-2+1)
Simplify.
AB = 2 / -1
AB = -2
So, your slope is -2.

i√5
steps:
negative square root is called a complex number
for a negative square root standard form means have an i in the number
i = √-1
standard form for a complex number is
a+bi
√-5 = √5 x √-1
i√5
