You know the number has to be divisible by 11. You also know the number is between 100 and 200.
You can list the multiples of 11 in this interval.
110, 121, 132...
You have your answer. The total price is 132 dollars, and the missing digit is 3.
Answer: B) 0.28
Step-by-step explanation:
Given that:
Lean/Healthy Overweight/ ObeseSelf Esteem Low 18 32 High 32 18
Overweight/Obese Lean/Healthy Total
Low 32 18 50
High 18 32 50
Total 50 50 100
the phi correlation coefficient is defined by Ф = √x²/n
where n = 100 ( total number of response )
x² = [(32×32 - 18×18)² × 100] / [50 × 50 × 50 × 50]
Ф = √ [(700)² x 100) / (50)⁴ × 100
Ф = 700 / 50²
Ф = 0.28
Therefore option B) is the correct answer
