Explanation

To find the range, subtract the smallest value from the largest value:

Maximum value = 28

Minimum value = 20

Range = Maximum value - Minimum value

= 28 - 20

= 8

Explanation

Identify the given values: The sum of observations is Sum=1500

. The number of observations is n=30 

Average = Sum of observations / Number of observations

= 1500 / 30

= 50

Explanation

Median is the middle value when data is arranged in order.

Ordered data: 63, 65, 66, 67, 69 → middle value is 66.

Explanation

Explanation

Specific death rate refers to the death rate calculated for a particular segment or subgroup of the population (e.g., by age, sex, cause).

It helps in understanding mortality patterns more precisely than the overall crude death rate.

Explanation

For a leptokurtic distribution, β₂ > 3:

β₂ = μ₄ / μ₂² > 3

Given μ₂ = 3.5:

μ₄ / (3.5)² > 3

μ₄ > 3 × 12.25

μ₄ > 36.75

Explanation

Step-by-step Solution:

Given numbers:

17, 13, 18, 17, 14, 18, 19, 17, 13, 16, 18, 20

1. Arrange in ascending order:

13, 13, 14, 16, 17, 17, 17, 18, 18, 18, 19, 20

2. Count the numbers:

Total = 12 (even number)

3. Median = average of the 6th and 7th terms:

6th term = 17, 7th term = 17

Median = (17 + 17) / 2 = 17

Explanation

Mode is the value that appears most frequently in a data set.

It represents the highest frequency among all values.

Explanation

To find the median, let's arrange the weights in order:

27, 29, 30, 32, 33, 35, 37, 47, 48

Since there are 9 values (an odd number), the middle value is the median:

The median is the 5th value: 33

Explanation

The probability of any event is always a value between 0 and 1, inclusive.

• 0 means the event is impossible.
• 1 means the event is certain
