Answer:
option (D) 16.5
Step-by-step explanation:
Data provided:
Sleep time of , X = 15.9 is at the 10th percentile
Standard deviation, σ = 0.5 hour
also,
10th percentile of normal distribution is
Z = F⁻¹(0.10)
or
Z = - 1.28 (Using Standard Normal distribution)
Now,
or
X = μ + ( σ × Z )
or
μ = X - ( σ × Z )
on substituting the respective values, we get
μ = 15.9 - 0.5 × (-1.28)
or
μ = 16.5
Hence, the correct answer is option (D) 16.5
Answer: The product xy is not constant, so the relationship is not an inverse variation.
Step-by-step explanation:
For it to be an inverse variation, the product of x and y must be constant.
- For the first row, xy=2(424)=848.
- For the second row, xy=3(280)=840.
- For the third row, xy=4(210)=840.
This means <u>the product xy is not constant, so the relationship is not an inverse variation.</u>
