Median is the "middle" number when arranged from smallest to largest.
Arranging in ascending order:

3rd number is 47
Hence, median is 47
Answer:
0.76m²
Step-by-step explanation:
In the above question, we are given the following information.
Radius = 0.4m
Height = 0.45m
To solve this question, The umbrella is CONICAL in shape and it has no BASE, we would be finding the lateral surface area of a cone. Since we are given height and radius :
Lateral Surface Area of a cone =
πr√(h² + r²)
= π × 0.4√(0.45² + 0.4)
= 0.7566m²
≈ Approximately = 0.76m²
Therefore, the amount of fabric needed to manufacture this umbrella is 0.76m²

Sample is the 118 people with eye cancer surveyed and 475 in control group without the disease.
b) Family history, parents having cancer, other habits such as smoking, or alcohol are lurking variables.
c) We can generalize the findings to all people by
i) increasing sample size. The maximum sample size the less the error.
ii) Samples taken at strictly random procedure without any bias
iii) samples taken over a spread population of various regions, countries, cultures, food habits, etc.
iv) Grouping into persons with smoking, with alcohol, etc will improve the results by reducing the variation due to lurking variables.
