Answer: Option E. None of above
Answer:
Step-by-step explanation:
x y = -5 y (x, y)
-1 -5 (-1, -5)
0 -5 (0, -5)
1 -5 (1, -5)
Slope between two points and is given by,
Slope =
Slope between points (-1, -5) and (0, -5) will be,
Slope =
= 0
Slope of the line passing through the given points will be 0.
Answer:
7/12 of an hour or 35 minutes
Step-by-step explanation:
Given Information:
Population size = N = 210
Mean height of women population = μ = 64.4 in.
Standard deviation of height of women population = σ = 2.9 in.
Sample size = n = 36
Required Information:
Sample mean = μx = ?
Sample standard deviation = σx = ?
Answer:
Sample mean = μx = 64.4 in.
Sample standard deviation = σx = 0.44 in.
Step-by-step explanation:
We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.
The mean of the sample will be same as population mean that is
μ = μx = 64.4 in
Whereas the sample standard deviation is given by
Where σ is the standard deviation of height of women population, N is the population size and n is the sample size.
The term is known as finite population correction factor and is used since the sampling is done without replacement.
Therefore, the standard deviation of sample is 0.44 in.
